This is an absolutely fantastic book, one I found it very hard to put down. The book is written from the point of view of shattered, broken Eve - she has amnesia, she's wearing a face not her own, she has disturbing yet beautiful flashbacks...which her "protectors" need to help them catch a serial killer - and it's written in such a gorgeous and immersive style that it shows the reader what it's like to be Eve.
I highly recommend this book to all lovers of contemporary fantasy (which it mostly is, but it does digress into other worlds towards the end).
Caveat: This book deals with themes of child abuse, albeit in a somewhat indirect and twisted way. This may make some readers uncomfortable.
