MARKED FOR MURDER 

When photos of Stephanie O'Brien are found in a serial killer's home, she must face the horrible truth that she's the next intended victim. She has nowhere to hide, nowhere to run—except to K-9 cop Rick Powell. As her self-appointed bodyguard, Rick will do anything to protect the innocent teacher—even keep his attraction at bay. He's known loss; he won't lose Stephanie. But the killer seems to anticipate their every move. And Rick fears he's never faced an opponent so cunning. One who won't stop till he has his victim right where he wants her…six feet under.
