A House of Ruin - Monica Corwin

She eats sins for a living. He's made of them.

Raven Vesper broke forty-eight angelic contracts and killed an archangel in the process. Her reward? Continued servitude to seven fallen angels, one year in each of their houses. Next up, the one who's already decided she's not good enough.

Seraph is the angel of pride-cold, precise, and utterly relentless. He won't let her use her rituals. Won't give her space. Won't stop looking at her like she's a puzzle he intends to solve, piece by devastating piece.

But Raven didn't survive this long by being obedient. And when she discovers the truth about her bloodline-a secret her grandmother died protecting-the real war begins. Not between Raven and Seraph. Between all of them and Heaven itself.
