Standing Watch by Terri Reed

To protect an innocent witness…a K-9 must sniff out a killer.

When K-9 task force officer Zach Kelsey’s estranged wife is attacked at a Mount Rushmore observation deck, he and his K-9, Amber, are quick to come to her rescue. He discovers not only that Eden, a park ranger, is carrying his child, but that she saw her coworker’s murder. As the only witness to the crime, Eden has no choice but to accept Zach’s protection. But with a ruthless killer ramping up his vicious attacks, they must put their differences aside to catch the murderer…before Eden becomes his next target.
