Book excerpt: Threesomes are hard, everyone says, but since kindergarten, Vanessa, Winnie, and Zoe--the End-of-the-Alphabet Club--have done everything together: sleepovers, trips to the library, games at recess. Yet now, as the world of ballet enters their lives, Winnie fears she will lose her two best friends. Simply told and illustrated with heartfelt, spirited drawings, this early chapter book explores the mysteries and joys of friendship.
