This is book number 5 in the Demon Trappers series.
Riley Blackthorne's life as a Demon Trapper is about to hit the wall. Knowing she will always be a target for those who want to exploit her "connections" with Hell, she's learning defensive magic. It seems the only way to ensure she and her fianc , Denver Beck, have a future together. But not everyone in Atlanta, or at the Vatican, is pleased by this news. In fact, some want to ban the use of all magic, and Riley would make the perfect scapegoat.
As a new demonic enemy stalks her, Guild politics roil the city, throwing the trappers into chaos. To protect herself and the man she loves, Riley will be forced to choose: continue in her legendary father's footsteps, or carve her own path. A path that may well lead to her losing everything she so desperately seeks to protect.
