Callie

He may be her first Greater Demon–but he will not be her last.

Then, on Valentine's Day 1929, seven men are lined up against the brick wall of a garage on North Clark Street and massacred—and it isn't long before Callie realizes she could have stopped it. But by the time she discovers the full truth it's far too late to extricate herself from its effects as a mere human.

Taking a bullet meant for Johnny Sinclair is not her idea of a roaring good time. Neither is learning he's not the "business man" he purports to be, but Mestopheles—demon of the Crossroads, collector of souls. But finding out she's a Keeper of the Flame, champion for humanity in the coming apocalypse, gives her the strength and drive to pursue him in a hunt that spans five decades and two cities—even as he hunts her in turn.
