Harry and Clare are stuck at home for their spring break. No exotic locations, no plane trips, no exciting plans. So they make their own fun: the living room becomes Mars, the diving board at the pool becomes a pirate’s plank and the local playground where the man-eating octopus lives. The trouble is, older sister Clare is the one making all the rules, and that means deciding on the game AND eating all the food. But Harry has a plan to turn the tables…if he can just keep his snacks out of the Abominable Snowman’s clutches!
