Everyone Has Their Demons — A.L. Kessler

Abigail Collins is no stranger to murder, but when a case hits close to home, she's forced to trust agent Liz Jefferson to solve it. Abby finds a distraction when the victim of a demon shows up in an apartment with no signs of the summoner or the beast, and the new case quickly leads her down a darker road than she expected. Meanwhile, trying to balance the new vampire politics that Levi throws at her is no easy feat. Ira is demanding a meeting under truce. Without knowing the full story, Abby goes in blind, hoping finally to have her shot at killing him.
