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 drover 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.
