Grug and his family, the Croods, are a very safe and careful cave family. Life isn't always fun, but they are alive. When trouble seems to be nearing their cave, they barricade themselves in. Eep, the daughter, has a spirit of adventure and sneaks out of the cave one evening in search of fun. She soon finds a friend to lead them on a wild adventure to safety. The vocabulary is appropriate for the age group specified. But even adults will enjoy reading this fun, fast paced book. Colored pictures in the middle of the book help the reader imagine the characters and anticipate the movie. Without seeing the movie, I can't judge how closely the book follows the script. But either way, young readers will fall in love with the imagery the author created about the characters. A web address gives the young readers more access to information about the movie and provides activities. Parents will appreciate the message of family and accepting others for who they are.Grug and his family, the Croods, are a very safe and careful cave family.
