Colton's Private Security (The Coltons of Dark Canyon #5)

He let her go once.
He won’t lose her now.

Since he left the military, Mark Colton’s work as a bodyguard has satisfied his need for travel and adventure. He’s on a rare visit back home when a dangerous criminal takes a nurse hostage. That nurse is Cassidy Garner, his high school sweetheart, and seeing her in the grasp of an armed villain makes his well-honed instincts kick in. After this close call, he’s determined to keep her safe—even if that means ignoring the once-in-a-lifetime attraction they both still feel. But what if it’s his past that’s putting her in danger?
