I don't feel like I have much to say in regards to a review. This was a quick read, and to be honest, I didn't connect with it enough to form a deep opinion of it's content. 
 The book, overall, was well written, but when it came to the much awaited "why," I kind of felt cheated. The entire 3/4 of the book held me in a suspenseful anxiety that I was CONVINCED would lead to a mindblowing reveal-I don't feel like that was delivered. Though, I am far from heartless. The reveal was NOT something to take lightly-I wholeheartedly believe in seeking help the SECOND your feelings lead to an inkling of suidical thought. I suppose I just wanted more from this book-character and plot wise..*shrugs*
