Having skimmed a dozen reviews that lamented this book's "sad", "heartbreaking" ending, I spent most of this book preparing for tragedy. There may have been some, but this is not a tragic tale in its whole, and certainly not in its ending. 

This is the perfect book. This is a book about everything. Grief, friendship, humanity, gaming. I couldn't have loved the ending more. Collaboration and kinship are more profound than romance.

Sam and Sadie getting together

would have ruined this story.

The characters were so well made. The symbolism made me want to ball up this book and eat it. I really don't know what else to say. I loved this book. I haven't felt this way about a book since I was 12 reading the Hunger Games.
