Elizabeth Bear's Undertow (a Philip K. Dick award finalist) is the book that fulfilled what I want in a book - it crystallized my amorphous ideas about what I wanted and literally showed me - it's eyeball-popping finale really melded the book into a cohesive whole, tied up the loose ends, and gave me the thrill I needed. As an author, she has always satisfied me (her Jenny Casey trilogy), but in this book she was in top form - it's semi-mystical beginnings, unsavory characters, and odd, Louisiana Bayou Company Town setting, plus a very unusual alien species, made the beginning questionable - what have I gotten my self into? Were Hammered, Scardown, and Worldwired a fluke - was that all she had? Well, Undertow answered that with a resounding NO!
One thing that stood out was that she used a different type of future - a non-Singularity future, which I enjoyed. So much SF these days, when dealing with the Far Future, uses that. But it is filled with lots of high-tech - wearables, the connex mentioned. Basically everyone, except a few who chose to live "off the grid" so to speak, are completely wired in - they get instant news, houses are responsive and security runs high. And the way the whole city/town can just pick up and move is sooo different. Even the aliens are (the information is dribbled out over the course of the novel) inventive and use all the possible elements that can be done - nothing about them are giant lizards, or talking trees.
There has been some negative comparisons to The Secret, because, as she is not a quantum engineer, her explanations of some of it's aspects used in the book are minimal - but as both a Hard SF nutcase, AND an under science-educated reader, it hit a chord - I loved not being overwhelmed with technical detail, but still be able to "follow" the idea behind the quantum theory, which is one of the reasons I got into Hard SF - Baxter's Manifold: Space was full of mind-boggling stuff, and although I didn't understand it all, I didn't have to - the mere idea that these things exist, or are theorized to exist, is enough to set your world on end.
Some reviews have focused on the use of the probability futures, and it's cursory explanations - they want more detail. I, on the other hand, don't need that - I just need the author to set me on the path, and get me fired up, and off I go. I LIKE not being in a lecture hall, but instead, given ideas that make me THINK, and want to run to my nearest Hawking book, or other QM one, and do some research on my own. Too much detail strays the story off it's path, IMO.
Undertow set the bar quite high for me, which is probably why I've been so hard on A Fire Upon the Deep by Vinge. This book makes the others look amateurish, dull, wordy and unimaginative. Undertow accomplishes in it's short (368) pages, what AFUTD (624) couldn't do in almost twice the length.
I urge you to give it a try - if you've read the Casey trilogy, it's nothing like it. This is NOT your grandmother's book. It's cool, mysterious, shadowy, full of fun, capers, plots and counter-plots, treason and treachery, and all set within an incredibly complex setting, more so as the book goes on, and as I have repeatedly said, the push to the ending is enough to make you think your trippin'.
So, do me and yourself a favor - if you like fresh, new, exciting, genre -bending SF/Fantasy (SFF), then read it. Support your local SF writer! If you prefer your SF to remain in it's cozy, set genre, then don't.
Have a wild ride (and stay on the horse - it might want to buck you off at first, but if you persevere, and are the kind of reader I mentioned, then the ride will be one worth all you've given it).
