Nym has always loved the stars.

It's in her blood: Nym is a Medyssian, a shapeshifter born with an irresistible wanderlust for the universe's depths. But that was before a ravenous predator called the Shadow drove her kind to near-extinction and her family into hiding—accidentally leaving her behind in the process. Now, she wanders the ether with nothing but a map full of dead ends, desperate to find her way home.

Aren has always feared the stars.

He isn't just the youngest member of the Celestial Company—the most skilled crew of mercenaries to ever sail the void—he's the only son of its ruthless captain, drowning in both the weight of her legacy and his secret fear of space itself. And if he can't prove himself a worthy successor soon, he'll be left behind completely.

When Nym saves Aren from the wreckage of a mission gone wrong, he sees helping her as the perfect opportunity to prove he's more than a weak link. But the Shadow isn't the only predator lurking in the deep, Nym is hiding a power she can't resist or control, and the Celestial Company itself has secrets threatening to fracture it from the inside. And as the monsters hunting them multiply, Aren must make a choice: protect the only family he's ever known, or save the only person who's ever made him feel fearless.
