Which Rebecca Stead novel won the 2010 Newbery Medal?

Rebecca Stead's novel When You Reach Me won the 2010 Newbery Medal. The mystery follows sixth-grader Miranda as strange notes, friendships, and an apparent time-travel puzzle converge in 1978–79 Manhattan.

The book was published in 2009 by Wendy Lamb Books, an imprint of Random House. Miranda lives on New York City's Upper West Side and is preparing for changes in her friendships while helping her mother get ready for an appearance on the game show The $20,000 Pyramid. The novel's tightly planted details become important as its mystery unfolds.

Stead drew inspiration from her childhood, an article about a man with amnesia, and Madeleine L'Engle's A Wrinkle in Time, which Miranda repeatedly reads. The Newbery committee praised the way the book's scenes and details serve both character development and the plot.

The year can cause confusion: the novel appeared in 2009, but it received the 2010 Newbery Medal, following the award's convention of identifying the announcement year rather than the publication year.
