House of Earth and Blood (Crescent City 1) paperback by Sarah J. Maas

Hunt Athalar is a notorious Fallen angel, now enslaved to the Archangels he once attempted to overthrow. His brutal skills and incredible strength have been set to one purpose-assassinate his boss's enemies, no questions asked. But with a demon wreaking havoc in the city, he's offered an irresistible deal: help Bryce find the murderer, and his freedom will be within reach.

As Bryce and Hunt dig deep into Crescent City's underbelly, they discover a dark power that threatens everything and everyone they hold dear, and they find, in each other, a blazing passion-one that could set them both free, if they'd only let it.

With unforgettable characters, sizzling romance, and page-turning suspense, this richly inventive fantasy series by #1 bestselling author Sarah J. Maas delves into the heartache of loss, the price of freedom, and the power of love.
