Audra Canton's suitors have an odd way of making their case: they keep shooting at her. The Colorado Territory of the 1870s is tough on women alone; the two Canton sisters have no one but each other after the death of their father. All the locals want to marry Audra for the Canton homestead, and they're not above scaring her into it. Audra needs help learning to protect herself and her sister.

That's when Lucas Blake drifts into Audra's life. She takes him on as a hired hand, though he's anything but. He's a lawman hot on the trail of a hardened criminal, and working the Canton homestead is the perfect cover.

But just when Audra thinks she's out of the line of fire, Lucas accidentally puts her straight into the sights of a new, more deadly gun that makes her drunken suitors look like toy soldiers. Now Lucas and Audra must fight for their lives—and each other.
