As soon as this crossed my desk and I read the description, I've been like this: 
 And let me say I was not disappointed. I sat down with the intention of just reading a few chapters before bed and ended up staying up way too late to finish the whole thing in one sitting. 
 Elizabeth Best is not what she seems. The Elizabeth that everyone thinks is one person is actually Lizzie, Betsy, and Ella. Clones from an illegal science experiment, they hide from those searching for them by each taking a different part of the day. They've been sharing a life since they were nine years old, but when Lizzie is forced to switch from first half to second after bombing a math quiz, she meets Sean Kelly and starts to question everything about the way that she and her sisters are living their lives. 
 Three girls posing as one?? How does that work?? I was beyond intrigued. Going in with such high expectations I was a little nervous about being disappointed, but I absolutely loved this book. There's a bit of instalove, but the way that it's handled actually reminded me of mine and my fiance's relationship when it first started back in high school (minus the I'm a clone part). It's a believable instalove, if that makes any sense. Sean Kelly is adorably nerdy and sweet. A new favorite YA boy (and shockingly he's not a bad boy!). I also love Lizzie. First person tends to drive me insane more often than not because we're stuck in the head of just one character, but I enjoyed Lizzie's voice. Too the point that I could not put the book down despite a need for sleep. 
 Definitely worth checking out!
