It's been 227 days since Essex Colony's last transmission…
Dispatched to the surface of Essex Prime and tasked with discovering what happened to the colony, Doctor Soran Ingram discovers that most of the colonists are dead and the surviving Executive Officer—Aline Aster—has turned into a ravening wolf-beast. The human survivors claim the XO and her Lunaran fellows went mad and killed everyone, but Soran has her doubts.
Following Aster's testimony, as well as clues left behind, Soran embarks on a fact-finding mission to retrace the colony's last steps before disaster struck.
She'll soon discover more than uncertainty lurks in the dark spaces of the world.
