Feisty Britt Kelly's life has blown up in her face. After her parents' divorce, her family moves from the suburbs of Trebridge into her half-sister's apartment in the projects. Britt must adjust to poverty, a new high school, and a step-mother who hates her and her younger brothers. But these aren't Britt's worst problems.

In the mage-fought Demon Wars, the minions of Prince Vetis have built a secret base in Trebridge behind the Kingscourt's battle lines. Like most humans, Britt didn't know demons existed before she was drafted to fight them with three new friends. Now she must fight against the evil that threatens her city.

As the demon forces grow, the Gargoyle Guardians of the city must teach the four teens to use enough "Grace" as a weapon to survive. Britt's new problem: learning to control her magical powers...in spite of Gillen, the gargoyle leader, pissing her off with his fussy rules and demands.
