"Join a lovable group of rock friends (and one wise little ladybug), on an fun and funny adventure about the importance in believing in yourself. Everyone's favorite rock group is back! When Tess, a tin foil ball, rolls onto the hill and meets Marvin, Ricky and the rest of the rocks, she immediately worries that she's not good enough: "Do you want to play?" asked Parker and Kai. "No thanks," whispered Tess. "I'm just rolling on by. I'm sure that you've noticed I don't really fit in. I'm not even a rock, I'm just made of tin. I'm not smooth and solid, and I'm not strong like you... I'm a tin foil ball - there's not much I can do." But when the rocks go off looking for a lost pebbles and get lost in the woods later that night, it's Tess to the rescue, as she realizes that everyone has value, and even a tin ball can be a rock star!"--Amazon.com.
