Parents don't tend to think of Jim Carrey as a children's book author (The Cable Guy, anyone?!), but the dad (and grandpa!) has published his first picture book, written for the preschool and kindergarten set. How Roland Rolls ($17) is the story of a wave who fears he'll die when he hits the beach, but ultimately learns he's part of the larger ocean. Told with Carrey's humor, the book is a lot of fun for adults and tots alike.
