Heads or Tails? 2 Oct. 2012
By Nickolas X. P. Sharps - Published on
Format: Hardcover
REVIEW SUMMARY: Back to the Future meets Three's Company in this heart-warming science fiction thrill ride.

MY RATING: 4 Stars

BRIEF SYNOPSIS: Ephraim thought his troubles with the multiverse were over. That is, until he has an unexpected reunion with a close friend from another dimension. Now Eph and his friends in this reality and the next must work together if they are to prevent the multiverse from hitting 'reset.'

PROS: Lovable characters, theoretical science, youthful energy, and complex relationships.

CONS: Loose ends tie up a little too cleanly.

BOTTOM LINE: Not just a great YA novel, Quantum Coin is a great science fiction novel in general. There is an abundance of heart and science to go around.

"I was promised flying cars and jetpacks," Ephraim said.
"You got alternate universes. Don't be greedy," Nathaniel said.

Ephraim Scott is just a regular guy. A regular guy that has traveled across multiple dimensions and ended the crime spree of a sociopathic alternate of his best friend. All that dimension hopping is now behind him and he is eager to move on with his life. Then Zoe, an alternate version of his girl friend Jena, crosses over into his reality. The multiverse is unraveling and Eph is needed to set things straight. The mission may not be so simple this time, given that meddling in alternate realities could be the very source of the problem.

Young adults are not stupid. Really, they're not. Just a couple months ago I read Fair Coin by E.C. Myers and it blew me away. Finally, a YA novel that broke away from the dystopia bandwagon and provided a science fiction journey that didn't skimp on the science! Oh, and the romance angle was even handled well, and this is coming from a guy who is extra hard on romances in fiction. Myers told a cautionary tale in the vein of The Monkey's Paw and The Butterfly Effect but with geek sensibilities. I had no clue that Quantum Coin would be released this year and it was a pleasant surprise to find the ARC sitting in my mailbox.

Quantum Coin sets the ball rolling pretty quickly, opening with the reunion of Ephraim and Zoe. This is followed by a refresher for those who may not remember parts of the first book. The refresher is organically integrated to the story so you don't have to worry about being yanked out of the narrative. Due to the nature of Zoe's return to Ephraim's reality, Jena gets involved. This is the start of an awesome love-triangle as Eph has to figure out which version he loves, all while trying to save the multiverse. Fictional romance usually irritates me to no end. So often the relationships feel forced and artificial. And that's just the regular relationships, not even taking into account the godawful love-triangles. The thing is I never felt bothered by the Ephraim/Jena/Zoe connection. To be honest, I couldn't get enough of it. The interplay between Jena and Zoe was funny and I actually felt invested in the choice that Ephraim had to make.

This could partly because the characters are so well drawn. Ephraim is a good guy. He has matured since the escapades of Fair Coin and learned that you can't solve life's myriad problems by wishing them away. He takes his mistakes and faults personally. He is also a teenage guy. Myers doesn't write an adult in an adolescent's body like a lot of YA authors. Eph is a true blue teenage male, with the same wants and desires. The banter between Eph and Nathan is hilarious to the point where I wish Nathan had a bigger role in the book. What is remarkable about the other characters is how individual they are, given the fact that they are alternates of each other. Zoe, Jena, and Doctor Kim are all quite unique despite having identical DNA. The same goes for Nathan and Nathaniel. This was an aspect that impressed me so greatly with Fair Coin and it only develops further in Quantum Coin. It is enough to get the readers wondering what their alternates would be like.

Also remarkable is the theoretical science that Myers works into the plot. Now that readers know that the coin is not magical the science is able to shine. Myers doesn't spend any time exploring the mechanical components of the Charon device, but he does probe into the theories behind the multiverse with aplomb. Quantum Coin is much heavier on the theory than its counterpart but is consistently enlightening and entertaining. There is enough detail to support the plot without overloading the novel with information. Had I read a book like this when I was younger I may have taken my science studies more seriously in school.

The plot is fast paced, with our heroes rushing from one universe to the next. Most of the universes they visit are similar to our own, nothing so far removed as a world where the people have superpowers. There are variations though, and there is a cause and effect correlation for such variations. Fair Coin was slightly tighter, given a true antagonist. The danger facing the multiverse this time around is much more immediate but it is also abstract. The process of solving the problem makes up for this mostly. There are sacrifices to be made but the ending is rather more wholesome than one might expect. For a series about choices and consequences it would have made sense to show some of the repercussions of saving the multiverse.

It's been a while since I took a lesson away from a novel but Quantum Coin left me appreciative of my own life in a whole new way. This is a mature look at the choices we make and the effects of those choices, told with geeky enthusiasm. Quantum Coin is part Back to the Future, part Three's Company, with a dash of The Butterfly Effect, a spoonful of nostalgia, a pinch of theoretical science, and a heaping helping of heart. This is the way sequels are meant to be and E.C. Myers has given me hope for the YA genre.

I Flipped a Coin & It Said You Should Read This Series 19 Oct. 2012
By Christina (A Reader of Fictions) - Published on
Format: Hardcover
Obviously, you should be cautious reading this review unless you've already read Fair Coin. I will keep things as spoiler-free as possible for book one, but that's pretty tricky. First and last paragraph will be spoiler-free totally. Now, if you've read my review for Fair Coin, you know that I quite liked it, but did have some reservations. Happily, Quantum Coin proves that the second book in a series can be stronger than its predecessor. If you were on the fence about reading Fair Coin, I'm telling you now that the awesomeness of this the sequel should cause you to choose the universe where you read E.C. Myer's Coin series.

Where Fair Coin has a fantasy feel for much of the book, Quantum Coin is straight science fiction, and I revelled in that, since I don't get nearly enough of that genre. In the first book, I had some difficulty grasping the concepts, though not to the point of frustration, but I felt less a fish out of water on this second go round. I'm not saying that I completely understood everything, but I didn't have any real WTF IS HAPPENING moments either. Myers does an excellent job keeping things on a manageable level of detail.

My main stumbling block in the first book were the characters, who, while not entirely unlikable, did venture into the unbelievable sometimes. They got better as they went along, and continued to develop and grow throughout this book as well. Ephraim and Nathan are way better in this book, and I liked how everyone got to be important at some time or other, though the Jenas really did rule the whole figuring things out part. Doug may be one of the cutest kids in literature, as he charmed my miserly heart. Dick made me laugh; you'll find out why towards the end.

I did not like the Jenas/Zoe, though. They are just not very nice women, despite being gorgeous geniuses. At least, Jena was less of a manicpixiedreamgirl this time. I will say, though, that Jena probably has the most in common with me, aside from bring super useful in crisis, Asian, and attractive to everyone. You know, little differences. Jena loves to read, and one of my favorite touches Myers put in the book was how when they went to different universes, books that aren't finished in our world ARE, like Jane Austen's Sanditon. I WANT TO GO TO THERE. For her love of fiction, I can't completely hate her. I mean, the world might be ending, but she still spends a lot of her time with her nose shoved in a book; I like those priorities.

The romance aspects I must admit I'm rather torn about. The whole love triangle with alternate reality versions of the same person is both very cool and very annoying. Honestly, I'm not quite sure how I feel about it. I think I'm coming down more towards the 'fascinating concept' side, just because Ephraim doesn't act like a complete jerk in that situation, when he could have tried to date both in some creepy, manly fantasy. Thankfully, he didn't do that, because I would have reached into the book and slapped him silly.

The beauty of Quantum Coin lies in the details. If you read closely enough, Myers throws in a bunch of nerdy wordplay and references, some of which made me laugh out loud, even though this isn't a humor book. Though I want to leave most of the references for you guys to find, I just have to share my very favorite one, because it was so subtle and wonderful. This is from the ARC, so it could be changed, but I hope it's not. High five for everyone who gets the reference!

"'Imagine: If shifting from one universe to another is like moving up or down to parallel layers, overlapping with one universe, then going to another timeline is like taking a jump to the left.'
'Or a step to the right,' Jena said wryly."

It's a truly rare thing to encounter a second book that improves on the first, but Quantum Coin truly does. On the down side, this series does appear to be complete. I've gotten so used to trilogies that I was totally expecting more. I will eagerly await E.C. Myers' next writerly endeavor!

If you're having girl trouble I feel bad for you son... 25 Oct. 2012
By Tom Braun - Published on
Format: Hardcover Verified Purchase got 99 parallel universes and a girlfriend in every one.

Quantum Coin is the follow up to Fair Coin, which was a fun YA romp in which a geeky kid named Ephraim Scott discovered a quarter in his locker that let him jump into parallel universes. And in some of them, Jena Kim, the girl of his dreams, actually liked him.

The sci-fi twist is that in a more futuristic version of their world, Jena, Ephraim and his best friend Nathan are reality-hopping explorers. The 'quarter' that Ephraim discovered is actually one half of a device keyed specifically to his biometrics that allows them to universe-hop.

But the three teens encounter alternate versions of themselves called 'analogs' in almost every universe they visit, and trouble starts when one of the Nathans turns out to be a psychopath who strands Ephraim in a terrifying alternate-reality.

By the end of Fair Coin Ephraim gets the girl (in this case a hard-edged 'analog' of Jena Kim named Zoe Kim), thwarts Evil Nathan, and returns to his home reality. The coin's power is used up and all seems to be restored to normal.

Quantum Coin picks up a year later. Ephraim is now dating the Jena Kim from his own reality and everything seems peachy. Until Zoe Kim shows up, having escaped from her own parallel universe, to tell Ephraim that things are falling apart and the Multiverse itself is at stake!

Yes, really.

Something is causing the fabric of the parallel universes to unravel and Ephraim and Zoe, with Jena tagging along, need to figure out what.

High-schoolers saving the very existence of the universe may seem a little bit cheesy, and it is, but this ludicrous plot-line is more than made up for by the joys of watching Ephraim squirm while jealous alternate-reality versions of his girlfriend fight over him. Although sexual tension abounds and all the characters are constantly talking about sex, almost no one ever actually does the deed.

Often when sci-fi stories feature teenagers, their personal dramas are groan inducing while the plot is fascinating. In Quantum Coin, it's the other way around. Author E.C. Myers draws vivid characters who relate to each other in realistic ways. He also makes their analogs believable. It's interesting meeting Ephraims, Jenas and Nathans who differ in dramatic yet plausible ways thanks to their experiences in their own universes.

But Quantum Coin has a much more sci-fi driven plot than its prequel, and here's where it stumbles. Ephraim and his friends are called on to help their older, reality-traveling analogs put the multiverse back to rights when things start going haywire. While the rules of universe-hopping were spelled out pretty clearly in the first book, in this one those rules pretty much go out the window. There are multiple controllers for changing realities and sometimes you don't even need one, and the more the mechanics of the Myers' multiverse are explained the less they make sense.

This book also suffers from a lack of a strong central villain like the first one had. There isn't really a villain in Quantum Coin, just some occasionally misguided people who are trying, along with the reader, to figure out what the heck is happening.

It all ultimately comes down to a choice for Ephraim: what version of his girlfriend does he really want to be with, and what version of himself does he want to be? This is a much more compelling story than the highly dubious multiverse plot. Fortunately the author realizes that by the end, and brings the focus back to where it should be: on Ephraim, Nathan, Jena/Zoe, and the choices they make.

Worth reading, but definitely pick up Fair Coin first.

Great Book! 10 May 2013
By Alisa Russell - Published on
Format: Hardcover
I found the the sequel to E.C. Myers' Fair Coin in the library a few weeks back and checked it out because I was curious to find out what had happened to the characters he had established so well in Fair Coin.

It is a year later. Ephraim has gone back to his home universe and has gotten together with Jena. They are getting ready for prom, and he thinks everything is normal. Not so. In the middle of prom, Jena's analog Zoe shows up from her universe and tells Ephraim there's a problem with the multiverse. This starts the next phase of Myers' story, and it's a doozy.

I enjoyed this book as much as I enjoyed Fair Coin. The world Myers created is even more complex and layered, but is still not difficult to understand. The characters are even more engaging, and he does a good job of keeping track who is who during the story, made more difficult, I think, by all of the analogs of the main characters speaking. I was very impressed. I don't know if Myers is planning on writing anymore stories in this universe, but I would read them if he did. I will also keep an eye out for anything else he might write. Great job!

Excellent Book 4 Jan. 2013
By Brother Bear - Published on
Format: Hardcover Verified Purchase
As in the first book there are plenty of plot twists that kept me from guessing what was truly going on. Most authors focus on what would happen next. The story is not a fairytale. There are parts not recommended for people who want an all round happily ever after. It does pose an interesting thought of the consequences of parallel universes and how they work.
