School’s out and summer camp’s in! When Marvin and his friends meet Joey, a lake monster with a loud mouth and few manners, it seems that Marvin is the only kid in camp who will be his friend. And Marvin’s friendship with the lake monster is causing ripples among his other friends. No one wants to be around the kid who cuts in line, or talks over them, or tells them what he really thinks about their art project. But Joey secretly wants only one thing: friends. Can Marvin help Joey learn how to make—and keep—friends? Marvin's hilarious doodles and diary entries chronicle his delightful adventures, misadventures, and eventual triumph in a funny, relatable way. It's the one series on ADHD and associated issues that kids will actually want to read!
