Cade and the Last Starship

After 400 years, you'd think there would be no secrets left on the Ark.The Ark carries the last of humanity to their new home on another planet... but in the meantime, Cade is bored. He wants something new. To go where no one has ever gone. To see what no one has ever seen.But not everyone wants him exploring. Why won't the Engineers let him see what's out in the uninhabited areas? It's mostly hallways and empty berths. There shouldn't be anything dangerous... should there?
