Guarding Bristol by Kaylea Cross

She was just trying to help him get back on his feet.
Once upon a time, Bristol Moreau managed to drag her late brother back from the brink of the abyss. So when she finds out that one of his former brothers-in-arms is living on the streets, she makes it her mission to do the same for him. But he makes it clear from the start that he doesn’t want her help—or anything to do with her. When she persists, it unleashes a chain of events that lands them square in the crosshairs of a deadly cartel. And now her only hope is the man who wants nothing to do with her.

Instead, she accidentally blew up his world.
It feels like every time former Ranger TJ Barros turns around, she’s there. The exasperating, stubborn, and gorgeous woman who refuses to take no for an answer. He shouldn’t want her—because he knows the scorching attraction between them could destroy them both. She deserves better than him, a broken man who’s spent the past year living on the streets. But now they’ve both got targets on their backs, and armed gunmen hunting them down. And just when he finally breaks away from her, things go sideways. Now she’s facing certain death because of him, and TJ will do anything to save her—even if it means trading his life for hers.
