The girls have been shipwrecked for nearly four months. They have made a temporary home on the island and have even begun to build a boat, to try to save themselves.

But can they finish the boat before some unforseen disaster occurs? And even if they do, will they be able to navigate the boat back home—six young girs...alone?
