Some lines aren't meant to be crossed.

I spent my life in the shadows-dodging danger, smuggling people to safety, and trusting no one. Especially not men like Adrian Vega, a relentless border agent who plays by the rules.

But one mistake changes everything.

Now, I'm a target. The cartel wants me dead, and my own brother is the one who pulled the trigger. I should run, disappear like I always do. But the only man standing between me and a bullet is the one man I can't trust.

Adrian should have arrested me. Instead, he let me go.

Now we're tangled in something neither of us can escape-too much heat, too many secrets, and a choice that could cost us both everything. Because the deeper we fall, the more I realize the real danger isn't the men hunting us.

It's him.

And if I'm not careful...

He's going to break my heart before the cartel can pull the trigger.
