When the USS Callisto is dispatched to investigate the disappearance of the USS Givens and a civilian research vessel, they uncover both ships dead in orbit, their crews having voluntarily abandoned them to join settlement on the planet below.

As the Callisto’s crew delves deeper, a strange telepathic presence exerts an inexplicable influence over all who encounter it, inspiring unwavering loyalty and reshaping lives.

With the fate of two crews and a pre-warp civilization at stake, the Callisto must confront the entity, navigate faith, free will, and the fragile balance of progress, and decide whether to leave behind a god who refuses to be forgotten.
