Xavier Oaks doesn't particularly want to go to the cabin with his dad and his dad's pregnant new wife, Nia. But family obligations are family obligations, and it's only for a short time. So he leaves his mom, his brother, and his other friends behind for a week in the woods. Only . . . one morning he wakes up and the house isn't where it was before. It's like it's been lifted and placed . . . somewhere else. When Xavier, his dad, and Nia go explore, they find they are inside a dome, trapped. And there's no one else around . . . Until, three years later, another family arrives. Is there any escape? Is there a reason they are stuck where they are? Different people have different answers -- and those different answers inexorably lead to tension, strife, and sacrifice.
