Stranded

Best Book Of 2013 by: Harrison Pazar

Summary

A family vacation becomes a game of survival!
It was supposed to be a vacation--and a chance to get to know each other better. But when a massive storm sets in without warning, four kids are shipwrecked alone on a rocky jungle island in the middle of the South Pacific. No adults. No instructions. Nobody to rely on but themselves. Can they make it home alive?

A week ago, the biggest challenge Vanessa, Buzz, Carter, and Jane had was learning to live as a new blended family. Now the four siblings must find a way to work together if they're going to make it off the island. But first they've got to learn to survive one another.
