Her troubled family history makes Noelle Harris’s return to Shelby for her sister’s funeral painful. But reuniting with Eli Colton, who’s investigating the serial killer responsible for her sister’s death, hurts even more. They’d been a couple in college, but Noelle ended the affair…breaking Eli’s heart.

But when they’re targeted by the killer, Eli must risk his heart to protect the woman he never stopped loving from the ruthless killer.

OPERATION RESCUE
by Justine Davis

When their fourteen-year-old son runs away, Blaine Everett agrees to help his ex-wife, Erin, search for the troubled teen, who they fear may be in danger. It’s been two years since the couple divorced, so working together will challenge their resolve—and their hearts—to stay strong. Blaine, a brave former marine pilot, comes with the Foxworth Foundation and its amazingly versatile canine Cutter—tracker, undercover agent, attack dog, therapist and, most surprising, matchmaker. Searching for Ethan, Blaine and Erin not only uncover the real reason they split—they realize that their mutual attraction never died.

CHRISTMAS SECURITY
by Lisa Childs

Biophysicist Dr. Priscilla Pell fears for her life—and the life of her unborn child. Living in the mansion where she’s still unwelcome among her late husband’s family, she doesn’t know whether the threats are coming from inside or outside. That’s why she hires professional security. She’s grateful for Blade Sparks’s around-the-clock protection, but his constant presence makes it impossible to ignore the effect he has on her. After a Christmas shopping excursion that should be a distraction takes a lethal turn, Priscilla and Blade can no longer pretend that their relationship is purely professional…

UNDER THE MARSHAL'S PROTECTION
by Anna J. Stewart

U.S. Marshall Howell McKenna has every reason to mistrust federal prosecutor Kara Gallagher. He’s also dedicated to his job. When she asks for his help convicting a mobster, he agrees—because it’s the right thing to do, and because her emotional attachment to the case means she’s in danger. Working together, they discover that putting their past behind them is easier than ignoring the heat that simmers between them. And, as an already menacing case takes unexpected twists, Howell’s not always sure that Kara wants justice more than she wants revenge…
