When You Reach Me by Rebecca Stead

Miranda is in Grade 6. She and her mother live in New York City. Miranda's favourite book is L'Engle's A Wrinkle in Time; she reads it over and over. Things are pretty normal in Miranda's life, except for the puzzle of anonymous notes that she has received. Notes with correct information about future events, like the fact that her mother has been selected to be a contestant in a tv game show.

This book is hard to categorize. It is a bit like Audrey Niffenegger's The Time Traveler's Wife, but suitable for much younger readers - Grade 4 and up. The opening quotation is from Albert Einstein: "the most beautiful experience we can have is the mysterious." That sets up this delightful tale perfectly.
