Mia Corvere is the child of a failed rebel, left to scrape a life from the gutter of a city built from the bones of a dead god. Her only inheritance is a rare and terrifying gift: she can speak to shadows, shape them, use them as weapons and shields. When that gift earns her entry to the Red Church—the deadliest school for assassins in the Itreyan Republic—Mia grasps the chance with both hands, knowing that graduation means one step closer to the consul and cardinal who destroyed her family. The Church demands she survive trials of blood, treachery, and magic in a place where failure is a corpse.

Mia is ruthless, brilliant, profane, and achingly human—a character who kills without hesitation but mourns every life she has lost. Her relationship with the shadowcat Mister Kindly (who eats her fear) and the darkness-wolf Eclipse grounds her even as her power grows incomprehensible. She is one of dark fantasy's most beloved antiheroes: morally compromised but impossible not to root for.

The trilogy takes Mia from the brutal tests of the Red Church to the gladiatorial sands of Godsgrave to a continent-spanning flight toward the truedark that could end the Republic's unending daylight forever. Kristoff uses the journey to slowly unravel the truth of Mia's shadow-affinity, the nature of her world's three suns, and a secret about her own existence that recontextualizes everything. Love, loss, and the question of whether revenge is worth its cost weave through all three volumes alongside astonishing set-pieces.
