Dweller in Darkness (Deadlights Duology #2)

All of Cassius Marius' life has been spent in service to the Pale King. Ever since his birth sixteen years ago on the night the Hero of Hathur died, his mother prepared him to join the Lightbringers: seven young men selected every equinox by the Church of the Pale King to descend underground to hunt and destroy the Dweller in Darkness, a chthonic entity the Church names as source of an unnatural blight ravaging Hathur and beyond, year after year.

Cassius has known since he could speak that he was destined to destroy the great evil poisoning his home. His inevitable confrontation with the Dweller on his holy descent changes him inside and out and puts him on a collision course with the Pale King he once worshipped. With his world and body crumbling around him, Cassius must choose between loyalty and honor, family and humanity, not to save his home. But to destroy it.
