Cold Fear — Susan Sleeman

A shared past…
Riley Glen's former girlfriend, recording artist Leah Kent, is performing at a summer concert nearby and calls to tell him she's in danger and needs his help. After the concert, he discovers her bending over a woman's dead body, and the woman has Leah's name freshly tattooed on her wrist. Leah claims she just found the body and didn't have anything to do with the murder. When two other bodies are found, both boasting Leah's name in bright ink on their wrists, she comes under suspicion for the murders. Riley jumps in to defend her from both an imminent arrest and a killer's deadly rage.

A new beginning?
Riley and Leah had once been a music team and deeply in love. But Riley's lifelong dream was to be a sniper, not a musician. He chose to follow his dream and has been successful in his career just as Leah has found success in hers. He still has feelings for Leah, but their lives are on vastly different courses. But when she begs for his help to clear her name and protect her, he agrees to do what he can. Riley soon discovers this killer is highly trained and vicious, and Leah won't survive another day unless Riley uses every skill he possesses to try to save her.
