The hollow crown of ashes

Kael Voss, an immortal enforcer cursed with a hunger for death, discovers Seraphine—a mysterious girl who can erase mortality itself—standing over a massacre in the supernatural underworld of Vorn. Together they must unravel who is summoning an ancient entity called the Hollow that feeds on immortals, while three factions hunt them and a toxic romance ignites between two monsters who may be the only ones capable of saving—or destroying—each other.
