Some kids spend their summer vacation at camp. Some kids spend it at Grandma's house. Wallace Bleff spent his out west...on a ride, a rope, and a roundup he'll never forget.

IT'S NOT EASY MOVING TIME AND AGAIN, but Tomas and his family are migrant workers who travel from state to state, helping farmers harvest their crops. When they arrive in Iowa for the summer, Tomas finds an escape from the scorching heat at the town library. And once inside, he also discovers a surprising world filled with dinosaurs, tigers, and a great new friend.
