Two people - one body.Two personalities - one outward appearance.Two minds - ONE person in control.It's not very often that I am excited to jump enthusiastically into a book because the first few paragraphs hooked me right from the start. After only a few sentences, I was raring to go. What's Left of Me started strong and kept me wanting more chapter after chapter.The book's very first words :Addie and I were born into the same body, our souls' ghostly fingers entwined before we gasped our very first breath. Our earliest years together were also our happiest. Then came the worries - the tightness around our parents' mouths, the frowns lining our kindergarten teacher's forehead, the question everyone whispered when they thought we couldn't hear.Why aren't they settling?Settling.We tried to form the word in our five-year-old mouth, tasting it on our tongue.Set-Tull-Ling.We knew what it meant. Kind of. It meant one of us was supposed to take control. It meant the other was supposed to fade away. I know now that it means much, much more than that.I read those first few words and immediately had to know more about these two girls sharing one body. Oh, and one more thing : All children are supposed to settle - or else.Yes, the dreaded "or else." We'll just say that it's not a good thing if the dominant personality can't kick the weaker personality's ass out of the picture. Picture scary hospitals and terrifying medical procedures and you'll have a small clue of what we're dealing with.~ Quick Summary : Eva and Addie have lived a lie for years, not telling anyone that they share a body. When they cross paths with a couple of other hybrid people like themselves, their quest for knowledge leads everyone down a dangerous path. ~What I liked the most about this book was that the voices of the weaker personalities were the ones pushed to the forefront. Perhaps in future books we'll get to explore the flipside, but I thought it was a great start for a series to see the world through the eyes of the people who were fighting to have some shred of control within their own bodies. There were several moments as I read in which I found myself asking the questions, "What would it feel like? What would I do?" Any time a book can drop me in the middle of a situation and have me imagining how the scenario would go if I was having to make the decisions, this is a good thing. What's Left of Me did have a character body-sharing experience similar to The Host but the story itself was not the same. There were no aliens and no body snatching in WLoM. However, I found myself perfectly content with the condition of the people in this story happening because of a genetic occurance. I've never quite read about hybrids like these. Two enthusiastic thumbs up for a promising start to a great series concept. Book 1's adventures left me wondering what's in store for installment number 2. I can't wait to find out!This book was provided from the publisher through Edelweiss in exchange for an honest review.
