My second Jodi Picoult book, and it was just as good as the first one (Leaving Time). 
 Emotional, dark and interesting. The story is told in two parts - 'before', focusing on Chris and Emily whilst she was still alive, and 'after', focusing on the fall out and repercussions for Chris and the families. Each chapter swaps between then and now, and the perspective swaps between all the main characters. I think this format really worked to give a greater understanding. 
 Teenagers Chris and Emily have been best friends their entire lives, and in love for the last few years. Their families live next door to each other and are all very close. Until the night that each parent receives a call from the hospital- Emily is dead from a gunshot wound to the head. Chris says they had a suicide pact but he fainted before completing his part. But is that what really happened? Emily's mum can't believe her daughter was suicidal and the police definitely aren't certain of Chris's innocence. What really happened that night, and what could make two seemingly happy, smart and well-off teenagers want to kill themselves?
