Rowan is an orphan with a Level Zero orb—a shelter no one believes can become anything more. When Count Caelan turns a family’s debt into a claim on Mira’s future, Rowan makes an impossible wager: build a greater keep than the count’s in thirty days, or surrender the only home he has.
The count has a fortune.
Rowan has a secret hidden in the stones everyone else throws away.
