The Seals of Solomon (Hellbound 1)

Host the demon.
Harness the power.
Pay the price.

Nathan Cross is your typical eighteen-year-old smart, sarcastic, socially awkward—and possessed by a demon who wants to turn people into blood art. Okay, maybe not so typical.

When his grandfather dies, Nate isn’t left money or a vintage watch. He inherits Astaroth, a Grand Duke of Hell. Ripped from his normal life and thrown into St. Michael’s Academy—a Catholic institution where the students are more dangerous than the curriculum—Nate is an outcast struggling with an immense power he can’t control.
But his deadliest enemies are not in the classroom. A shadowy cult known as the Sect wants the demon inside him, and they’ll stop at nothing to get it. To protect those he loves, Nate must embrace his dark companion, master its power, and risk what’s left of his soul.

Perfect for fans of dark fantasy, magic schools, morally grey heroes, and power systems with teeth, The Seals of Solomon begins a series where salvation and damnation wear the same face.

Welcome to Hell School. Try not to break too quickly.
