In the Presence of My Enemies (An Emily O'Brien novel #5‪)‬

Carolyn Mercer is desperate. Her perfect life is about to be ruined unless she falls in line with a self-help group she joined with her new husband. Backed into a corner, she can think of only one person to help her escape her situation – reporter Emily O’Brien, a friend of her ex-husband who blames her for the breakup.
While the two aren’t exactly enemies, they’ve never been friends. Still, Carolyn’s problem isn’t one Emily can leave her to face on her own. Joining the group to see if she can dig up some dirty laundry, Emily finds more than just con men bilking the gullible. The leaders have tapped into dark forces and they will go to any lengths to get what they want.
The deeper she gets, the higher the stakes, with Emily needing to call on her faith to find a way out. But, despite her best efforts, Emily’s intervention leads to deadly repercussions, for her, for Carolyn and for the people they love.
