3.5/5 stars.What's Left of Me is one of those books that I felt everyone but me had already read. Not only had they read it, but they'd raved about it so much it made me nervous to actually pick it up. And while I don't think I ultimately liked it as much as most folks have, once I got past a rather slow start, the book had nice flow, a unique plot, and intriguing characters that I did end up ultimately enjoying.This book is told from a unique perspective, because for much of the book, Eva - the recessive soul who was meant to die away, but didn't - isn't in any kind of actual control of the body she shares with dominant soul, Addie. That set-up made for unique storytelling that was very much focused on Eva's feelings and Addie's actions. One thing I wish was explained in more detail is how the world came to be this way. Is this our world that's been changed in some way? Or is this a made-up world in which the way we live and are never existed in the first place? I didn't feel that this information was explicitly stated, and made for a lot of questions on my part, and one of the reasons I wasn't completely sold on the story at the start. There is a lot of talk about the scary dangerous hybrids (which Eva and Addie are, although they live in secret) and the effects they've had on the rest of the world, and there's talk about the Americas (which are North, Central and South America all rolled into one giant super-country), but no actual explanations of how it all came to be. I want explanations! Call it the part of me that loves history, but I just feel like it would have really grounded the story and made it more relatable. But then again, that could just be me.Around the 20% mark, though, the book picks up in action, because Addie and Eva are shipped off to a rather frightening clinic due to a suspicion that they are indeed hybrid. The rest of the book is spent with them trying to figure out what's going on at the clinic, and trying to find a way to escape. There's also some romantic developments between Eva and Ryan, made all the more intriguing because Addie isn't at all interested in either Ryan OR his other soul, so she's definitely fighting Eva at every step, even if it's not intentionally. There's also the obvious give and take necessary as Eva becomes stronger, which adds tension to the girls' relationship and makes sharing a body even trickier. The sequel to What's Left of Me seems to focus even more on the girls' issues, so I'm looking forward to seeing how the author has taken that concept and expanded on it.All in all, while I wasn't completely in love with What's Left of Me like most people seem to be, I did find the book compelling and unique in equal measures. Eva is a wonderful narrator, and I liked watching her growth and strength. She and Addie are definitely two totally different girls, so the fact that they have to share a body - and only one can be in control at a time - makes for interesting developments that you definitely don't see every day. I'm looking forward to reading the sequel and seeing how their journey progresses.***To see more of my reviews, please visit me @ Read and Reviewed!
