Guarding Teagan by Kaylea Cross

She’s out for justice.
Teagan Kim is on a mission to find her cousin’s murderer, the same one she suspects nearly killed her. She’s used to operating on her own, but the DEA assigns her a bodyguard for a job she’s handling—and he turns out to be the man she had a one-night stand with the last time she was in town. Now they’re forced to work together as she hunts down a murderer. And when the danger closes in, her sexy one-night-stand-turned-bodyguard is all that’s standing between her and the people who want her dead.

His job is to keep her alive long enough to get it.
Decker Abrams is Crimson Point Security’s newest personal protection specialist, and he’s just been handed his first assignment: Teagan. The woman who saved his sister’s life and then ghosted him after the hottest night of his life. She’s just as much a mystery to him now as the first time they met. He wants to know why she left without a word, but he’s got a job to do and refuses to let things get personal. Except everything about Teagan feels personal. And as the danger mounts, they’ll have to learn to trust each other if they want to make it out alive.
