Lucas has dinosaurs on the brain, but he's a little short on friends. When he gets a new book on how to make model dinosaurs, he's inspired to make one immediately.

But when he mixes the liquid into his papier-maché goop, he gets much more than he bargained for, including the most unlikely friend.

His mother has moved him across the country to be near to his grandfather who insists on playing (and winning) endless games of Crazy Eights and whose ornery, ancient dog makes Brady's life miserable. Abra, next door, is nice to him, but she dresses like a witch and she's a girl. The only way that Brady can see to make real friends in his new home is to enter the upcoming dog show, but how is he going to do that without a dog?
Jake and his younger brother Tommy are visiting family at a beach house on the coast. Having already lost a race to his cousin Lexie, Jake can't resist a second chance at victory when she challenges him again. Only this time it's a boat race-to the legendary Smuggler's Cave and back. The ocean is deep and choppy, and the boat is harder to control than Jake thought it would be. When he and Tommy reach Smuggler's Cave, the unthinkable happens. The boat capsizes, and they are swept into the cave. Lexie comes to their rescue, but the rising tide prevents them from escaping, and the three of them soon realize they are trapped.

When forty thousand dollars is stolen from the till, and his friends are under suspicion for the theft, boring is starting to look good. But Clay is certain that the mask and the thefts are connected, and he's determined to solve the crime.
