Heavenly Bodies meets Divine Rivals in this star-lit romantasy about a girl who tried to end the world—and now has to save it.

In Velandor, where magic is ruled by the constellations, Celestine Savareau rots in prison after a failed attempt to end the world. In exchange for her freedom, she begrudgingly joins the Nightguard who protect Velandor, even though it means fighting her ex-lover and accomplice, Aire. But within the Nightguard, Celestine plots to reunite with Aire and destroy the world once and for all. She's just not sure if Aire wants to destroy her, too.

Nightguard Kivessin would rather die than work with Celestine, who he blames for his mother’s death. But when he learns that helping Celestine means taking her down if she goes rogue, he gladly agrees.

As they train together, Celestine must exploit her past connection with Aire to stay one step ahead of everyone who wants to see her fall. If she fails, the world will end—and she’d hate to die without exploring the undeniable tension that lingers between her and Kivessin.

Together, Celestine and Kivessin discover: Celestine might not be the monster they thought . . .
