Sera and Ransom’s fates are decided in this thrilling third and final book in the New York Times bestselling City of Fantome enemies-to-lovers romantasy trilogy perfect for fans of Margaret Rogerson and Caraval . War has come to the kingdom of Valterre. Led by the self-proclaimed People’s Saint, a gathering faction plans to seize control of the kingdom and the lands beyond. Outwardly united against this common threat, Sera and the newly-Sainted Ransom find themselves divided by their diverging destinies. The more Saints that Sera creates, the more her life force ebbs away. The people look to her as a leader and a symbol of peace, but is the cost too high? Meanwhile, Ransom’s powerful and terrifying shadow-magic threatens to pull him even deeper into darkness. Perhaps, to save Sera, his true destiny is to become the villain.
