I randomly stumbled upon When You Reach Me in a used bookstore in Japan and picked it up for my middle grade students. Having no idea what I was getting myself into, I was very pleasantly surprised by the readability and intrigue of the plot. Part adolescent angst/part time travel mystery, this book presents small pieces of the story in short chapters that leave you wanting more. I think my students will real enjoy it, though the theories of time travel will likely blow their minds.
