Book 2: The Cathedral Beneath Rome. The Veiled Hunter Chronicles, #4

After surviving the darkness of Black Hollow, Sister Evangeline Nocturne is sent to Rome, where ancient bells are ringing beneath the city and sealed catacombs are beginning to break open. Deep below the holy streets lies a buried cathedral no living map can find-a forgotten place built to imprison monsters older than prayer. But now the seals are failing, and something powerful is waking beneath stone, relics, and blood.
With new allies at her side, Evangeline must face undead priests, bone beasts, shadow wraiths, corrupted relics, and the terrifying Bone Bishop, an underworld enemy who knows the secret of her forbidden bloodline. As Rome begins to fall into fear, Evangeline discovers the buried cathedral is not only a prison. It is a weapon. Dark, intense, and action-filled, The Cathedral Beneath Rome continues The Veiled Hunter Chronicles with stronger monsters, deeper secrets, holy machines, dangerous betrayals, and one false nun fighting to stop the underworld from rising beneath one of the world's most sacred cities.
