Eleven-year-old Tommy's classmates are annoyed with him for always goofing off and disrupting class. Tommy has Attention Deficit Hyperactivity Disorder (ADHD), which makes sitting still, being quiet and focusing on the teacher difficult. His friends, brothers Aiden and Jacob, want to help. But Tommy's two buddies are more than just siblings, their actually Ninjas! Their power comes from the magic of two ancient Ninja rings that their great-great-grandfather, an explorer, passed down to them. Aiden and Jacob's Ninja rings give them the power to understand how Tommy's ADHD brain thinks differently. They help him adapt to challenges in the classroom, on the playground, and at home. Through the powerful bonds of friendship, Aiden and Jacob learn that Tommy's different way of seeing the world gives him some superpowers, too! Blending humor and action-hero fantasy, Entering the Deep Unknown (The Amazing Ninja Brothers), is the perfect read for kids, parents, friends and teachers navigating the challenges and opportunities of ADHD.
