Kevin can't get to sleep at night until he straightens his chair and his books. He checks under his bed for a light he knows isn't there, and then, a minute later, he checks again. Kevin knows these actions don't make sense, but the worry thoughts keep coming.

When his parents realize that Kevin has too many worries, they take him to talk to a therapist. She tells Kevin and his parents that Kevin has a condition called obsessive-compulsive disorder (OCD) and that, more importantly, he can be helped. Hardcover.
