Catherine Deverell is not insane. She is merely misunderstood. Born hollow—a soul-eating void that makes gods look away and demons pray—she wears a gentle mask to survive. But when the Crown Prince invites her to a gala then vanishes, leaving only a bleeding feather, Catherine becomes the prime suspect. Now she must solve his murder while hiding her true nature: a woman with fractured selves that emerge through wine, near-death, and hunger. Everyone who loves her dies. Everyone who sees her truth goes mad. And the deeper she investigates, the more she realizes—she wasn't born a monster. She was made.
