Lethal Edge by Kaylea Cross

A diehard romantic looking to start over in a small town.
Dr. Nina Benitez might be an astrophysicist and a scientist down to her bones, but she also believes in true love and happily ever after—and won’t settle for anything less. After a rocky end to her first semester teaching at the University of Montana, she’s looking forward to a new school year and a fresh start in the small town of Rifle Creek. When she meets her roommate’s work partner, a sexy, hard-edged detective, Nina is immediately intrigued. However, it’s soon clear they’re like oil and water. But when she’s confronted by the painful past event she wanted to forget, she faces an even greater danger. A predator is bent on silencing her forever, and Nina’s only hope of survival is the unattainable man who’s captured her heart.

A cynical cop determined to guard his heart.
Tate Baldwin has dedicated his life to serving and protecting, first in the military, and now as a detective in Rifle Creek. Badly burned by his last relationship, he isn’t looking to get involved with anyone, especially a brilliant college professor who seems to have her head in the clouds. Yet even Tate can’t deny the attraction between them that soon grows into something more. And when a secret from her past triggers a lethal threat, Tate will risk everything to stand between her and the monster who wants her dead.
