New York Times bestseller Lauren Myracle’s long-awaited prequel to Eleven!

Winnie Perry is turning ten and ten is BIG. It means double digits, more responsibility, and being an almost-middle-schooler. Ten means that Winnie can handle anything, even a three-year-old baby brother and a practically teenage (and acting like it) older sister. And with her best friend, Amanda, by her side, Winnie plans on enjoying every last second of her last year in grade school.
