Four years after his children's book debut with 2019's Rumple Buttercup: A Story of Bananas, Belonging and Being Yourself, author (and Criminal Minds star) Matthew Gray Gubler returns with his follow-up: The Little Kid with the Big Green Hand. Published through Amulet Books -- an imprint of Abrams Books -- the new children's book is bigger and more ambitious. Gubler writes and provides his own illustrations for the story. While the gorgeous hardcover physical edition may come with a steeper price tag, it is a solid read and looks great on a shelf.
