If you loved Julie Kagawa's Iron Fey series following Meghan, and were feeling a little sad to have reached the end of the series (they need to invent a term for when you get withdrawal symptoms for your favourite books as for me it is a common ailment)... fear not the world of the Fey is back in all of its colourful, if slightly twisted glory!
This time it is told from the point of view of Ethan, Meghan's little brother (if you have read the previous series, Ethan was the little 4 year old boy who started Meghan's adventure). Ethan has grown up into a sullen and resentful teen, shaped by his life of trying to avoid the Fey that only he can see. Despite being a bit of a whiny child at times (especially when he is reunited with his sister for the first time in years) you can understand why he acts the way he does, and can't help but love that he still tries to protect everyone. Kenzie, the lead female character and love interest for Ethan, is a feisty and stubborn girl who you can easily empathise with... hopefully the relationship between the two will develop more in future books.
The only flaw for me is that there wasn't nearly enough Ash... which I guess is right as it's not his story, but still I miss his snarky comments and attitude. However, you may be happy to know that Puck appears twice within the journey for brief fighting genius, and Grimalkin, one of the best characters ever to be written who is also a cat (well technically a cait sith), takes over his trusted role as guide through the trods of the NeverNever and is featured a lot in this story.
In summary, if you read and enjoyed the previous Iron Fey series, buy this book as you will love it. If you haven't read the previous series... Why on earth not - go read it now. While you technically could read this book on its own as most of the world is described, there are so many references to the other characters that you will not enjoy it half as much, so I strongly suggest reading them first. The reading order for the other series is:
1. The Iron King
1.5 Winters passage (a short novella in between books 1 & 2 - while not necessary I would definitely recommend reading)
2. The Iron Daughter
3. The Iron Queen
3.5 Summers crossing (another novella - didn't really add much to the story, but worth reading for more time with Ash and Puck)
4. The Iron Knight (possibly my favourite book as it is from Ash's POV.... swoon!)
4.5 Iron's prophecy (novella that leads into the Lost Prince)
(All of them are available together The Iron Legends (Iron Fey (Quality))
