In the Skull Queen's domain, death is a gift, and he holds the blade.

Reaper is the perfect assassin: undead, emotionless, and immune to pain. He knows nothing of the life he surrendered his heart to escape, only that his purpose is to sacrifice the living for the Skull Queen’s glory. Every night brings the same rituals, the same bloody offerings. Until his queen demands he do the impossible…

Steal the soul of the immortal rival ravaging her lands, and in return, ascend as her eternal champion.

Bound to the Skull Queen’s will, Reaper seeks the help of Sower—the fierce priestess who sculpted his unliving form—to master the dark key to his foe’s soul. But when that same key unlocks the scars of their forgotten lives and reveals their target’s true identity, Reaper and Sower find themselves trapped between life’s bonds and disloyalty’s cost. Only together can they unravel their queen’s deception, break their deathly pacts… and restore the heart he lost.

Sleep Token meets Throne of Glass in this fantasy epic where vampiric overlords reign, veiled secrets cut deep, and love is as dangerous as pain.
