This psychological sci-fi thriller from a debut author follows one doctor who must discover the source of her crew's madness...or risk succumbing to it herself.

Misanthropic psychologist Dr. Grace Park is placed on the Deucalion, a survey ship headed to an icy planet in an unexplored galaxy. Her purpose is to observe the thirteen human crew members aboard the ship - all specialists in their own fields - as they assess the colonization potential of the planet, Eos. But frictions develop as Park befriends the androids of the ship, preferring their company over the baffling complexity of humans, while the rest of the crew treats them with suspicion and even outright hostility.

Shortly after landing, the crew finds themselves trapped on the ship by a radiation storm, with no means of communication or escape until it passes - and that’s when things begin to fall apart. Park’s patients are falling prey to waking nightmares of helpless, tongueless insanity. The androids are behaving strangely. There are no windows aboard the ship. Paranoia is closing in, and soon Park is forced to confront the fact that nothing - neither her crew, nor their mission, nor the mysterious Eos itself - is as it seems.
