In a world where time is a tapestry fraying at the edges, Kael Vritra sells his soul to survive. A demon-tainted mercenary with crimson eyes and arms etched with cursed sigils, Kael can sever the threads of fate itself—a gift that leaves cities in ashes and his name scrubbed from history. But when a botched massacre marks him for death, the Infernal Cartography offers a deal: kill Elyra Voss, a celestial weaver who stabilizes timelines, and his sins will vanish.
The mission goes wrong.
