Recursion

Adult sci-fi doesn't tend to be my thing, but I enjoyed this more than I was expecting to. With enough suspended disbelief, especially in how the story resolves, I was compelled to keep reading until the end. The story was twisty and interesting, with each part (6 in all) revealing another telescoping layer of the world he's built. My students that have read it said they were confused, so I'm not sure I'd recommend it for YA, but I don't think I'll forget this book.
