It’s easy to understand why wiggly Kaline Klattermaster wants to squirm away from his life: Already struggling with his inability to sit still or stay quiet, now his dad is gone and his mom won’t say where. To escape the chaotic world of his mother’s reign, Kaline thinks up a perfect hiding place–an imaginary tree house complete with 100 puppies and two older brothers who give him advice. Like Joey Pigza in Jack Ganto’s bestselling novels, Kaline has ADHD, making him all the more relatable to young readers, who will empathize with and cheer for him as Kaline finds the courage to leave the tree and face the real world.
