The Pregnancy Plot (Harlequin Intrigue Series #1584)

An undercover agent has one assignment: protect a pregnant woman who may know a lot more than she's telling… 

Nina Moore has no idea her life and the life of her unborn child are in danger. She only knows she's grateful for the handsome handyman helping her restore her bed-and-breakfast. But Jase Bennett isn't the average jack-of-all-trades—he's a special ops agent assigned to protect Nina from Tempest, the organization responsible for Nina's ex-fiancé's death. Getting close to the vulnerable beauty is easier than Jase expected…too easy. And when "fake fiancé" is added to his job description, the jaded agent is in over his head. But with the body count rising, Jase must risk it all to save Nina and her baby from Tempest's twisted plans…
