The last Cody heard from her best friend Meg was Meg's suicide note. Cody is stunned: she'd had no idea Meg was feeling so terrible; college separated them in a way that Cody was still trying to work out. But... why did Meg do it? What was her life really like? Who helped her with this huge, irreversible decision? 
 More than anything, this book is emotional. Like, I can't even talk much about the plot, because it's mostly about the palpable, visceral grief and guilt Cody feels. Cody wants to find whoever is responsible for encouraging Meg to kill herself, but it's only because she wants to be able to blame somebody besides Meg. 
 I could have done without the romance (can't two people of opposite genders remain platonic friends?) but I'm impressed with the ultimate directions: suicide isn't anyone's fault, and depression is a horrible disease and not a moral failing.
