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 their last year in elementary school.

This prequel to the New York Times bestselling Winnie Years series will thrill the tweens who grew up with Winnie and introduce a whole new generation of readers to a heroine they can grow up with.
