Siren's Secret (Harlequin Nocturne)

In Debbie Herbert's debut novel, there are two secrets, each one with a deadly consequence… 

Shelly Connors's worlds—on land and in the sea—are turned upside down when an evening swim turns into a nightmare. On a sweltering night deep in the bayou, the mystical mermaid witnesses a horrifying act. With a monstrous killer now hot on her trail, her life and the lives of her kin are in jeopardy. 

Terrified of becoming the next victim, Shelly has no choice but to turn to Sheriff Tillman Angier. Tillman has had his intense gray eyes on the sultry honey-haired beauty for a while. The feelings are mutual…and impossible to ignore. But he's determined to solve the murders, and he knows Shelly's hiding something. Can she trust him with her deepest secret?
