Sophie's lost in the jungle, and the sun is going down... Sixth-grader Sophie Washington, her good friends, Chloe and Valentina, and her parents and brother, Cole, are in for a week of adventure when her father signs them up for a spring break mission trip to Costa Rica. Her dreams of lazing on the beach under palm trees are squashed quicker than an underfoot banana once they arrive in the rain forest and are put to work, hauling buckets of water, painting and cooking. Near the hut they sleep in, the girls fight off wayward iguanas and howler monkeys, and nightly visits from a surprise "guest" make it hard for them to get much rest after their work is done. Then Sophie and friends take a wrong turn in the jungle and things get even more wild...
