So in my review of If I Stay, I said I wasn't entirely sold on Mia's relationship with Adam. Where She Went is from Adam's viewpoint and I'd like to state that I am now 100$ pro-Adam. Holy cats, am I ever. 
 This book is different from If I Stay, but it's also the same. I can't really explain it very well, but trust me. Kept me up Sunday night and I finished it first thing Sunday morning--that's really the best litmus test.
