When You Reach Me by Rebecca Stead, recommended by Tina

The Newbery Winner!

Beautifully-written story of a sixth-grade girl who starts receiving strange letters that say "I'm coming to save your friend's life, and my own." Do they have anything to do with her favorite book, A Wrinkle in Time? Meanwhile Miranda's best friend stops speaking to her, the homeless man on her block mumbles weird things, and she's tutoring her single mother for her upcoming appearance on the $20,000 Pyramid. Fascinating plot and characters.
