"The Creeper family is planning a month-long summer vacation! But where will they go? On a road trip across the Overworld? Backpacking in the Extreme Hills Campin out in caves? Gerald and his sisters can't agree! When Dad suggests they do all three, Gerald hops on board. But he quickly realizes that the only thing worse than being stuck with his sisters at home is being stuck with them in a minecart for hours on end!" -- From the publisher.
