This was a book that probably should not have worked for me. It's the story of a young man whose descent into mental illness is marked by the appearance of two future selves interrupting his present, and the two friends who try to save him. It's chaotic, and unpredictable, and genre-fluid, and honestly the three main characters were pretty unlikable for a lot of the book. It was also one of the most insightful looks into mental illness, and into being a friend of someone with a mental illness, that I've ever read. It's hard to even recommend because it's so unusual, but I honestly couldn't put it down.
