The Mysterious Stranger by Ainslie Paton

For Rory Archer, going deep under cover with her best friend Zeke Sherwood to bust a doomsday cult was a way of making up for her unprofessional behavior after a relationship breakup with her boss, Zeke’s older brother. All she had to do was act her part, find the evidence they needed to tear down the cult and help the people who’d been gaslit into joining to start new lives.

It was a far cry from the usual work she did, conning arrogant mega-rich men out of ill-gotten money to spend on deserving causes. And with Zeke by her side, it would be a blast.

For Zeke Sherwood, busting the cult was the easy part, even if it meant no way to feed his addiction to Frappuccinos, but surviving months, partnering the woman he’d been in love with forever would be the toughest job he’d ever signed on for. He and Rory had never been anything more than sidekicks and Zeke had given up thinking they ever would be.

But inside the cult, the truth is stranger than fiction, drawing them closer until uncertainty strips away old patterns of behavior and longing and lust bloom, bringing with them the danger of discovery and the fear that none of the new love they feel for each other is real.
