Sometimes facing your demons is literal.

A holy relic of terrible power is hidden somewhere in Boston. Worse, the forces of Hell itself are after it. Cassiel faces the very thing she fears most: a charming, intelligent, and likeable demon she knows she can't trust. Whatever his motives, Asakku is the only lead she has.

Working with friends both new and old, Cassiel finds herself in dire straits: few allies, no answers, and far, far too many enemies.

With her back against the wall, Cassiel must decide if Asakku is lying. Or, worse, if he's telling the truth.
