Siren Song by Debbie Baldwin

Leo “Ren” Jameson is a Navy SEAL with a mind as sharp as his combat skills. A tactical genius, he’s always one step ahead.
Until her…

For months, Ren has been drawn to demure CIA analyst Sofria Kirk, but their relationship fizzled before it really began, and Sofria left the country for a new job. That’s when Ren discovers Sofria was not who she claimed to be. Sofria Kirk is actually a government agent named Stella Keen who has been sent to spy on him and find out who is stealing the research for Ren’s top-secret drone project.
Determined to confront Stella and get answers, Ren embarks on a relentless pursuit. As Ren digs deeper, the mystery grows more dangerous. A traitor is selling government secrets and targeting Ren and Stella. With danger closing in, the pair escapes to a clifftop house in a remote Maine fishing village, where Ren quickly realizes Stella Keen is nothing like the bookish introvert she pretended to be. Brash, sultry, and constantly pushing his buttons, she’s everything Sofria Kirk wasn’t–and everything that was missing. Ren is torn between his anger toward the woman who deceived him and his all-consuming attraction to Stella.
The clock is ticking to find the traitor.
With an assassin closing in, Ren and Stella work to solve the mystery. As the sparks between them burst into flame in this hypnotic clifftop setting, Ren and Stella must capture the spy and unravel the tangled knot of their attraction.

This high-octane, twist-filled romantic thriller is perfect for fans of Mr. and Mrs. Smith, Jack Reacher, and authors Nora Roberts, Catherine Coulter, and Sandra Brown.
