House of Earth and Blood

Book one in Sarah J. Maas's #1 bestselling adult fantasy series, Crescent City. Half-Fae, half-human Bryce Quinlan has built a life of work by day and partying by night in Lunathion, until a demon murders her closest friends. When the killings start again two years later with the wrong person behind bars, Bryce is pulled into the investigation alongside Hunt Athalar, a Fallen angel enslaved to the ruling Archangels. Together they dig into a conspiracy that threatens everyone they love, and into a slow-burn attraction neither one can outrun.

Urban fantasy world-building, found family, and a grief-driven mystery open Maas's first foray into adult fantasy romance.
