Nothing is as it should be.

After weeks of boredom, Andi is excited when the Surveyor is called upon to rescue a freighter that mysteriously vanished in uncharted space. Excitement quickly turns to unease when the ship encounters an unknown phenomenon-a cloud that appears not to exist. But with the freighter's crew in danger, the Surveyor has no choice but to venture into unknown territory.

As soon as they enter the cloud, its unstable effects wreak havoc on the ship.

They're flying blind. Every piece of equipment is malfunctioning. And every member of the crew is unable to think straight or act like themselves-except Andi.

Now she's expected to guide them through the predicament with no previous command experience and no one to turn to for support. And with each passing hour, it becomes clear that if they don't escape the cloud soon-they won't escape it at all.
