A guarded heart is a lonely heart . . . Piper Davies is a leading researcher in the fields of viruses and nanotechnology. All she ever wanted was to help save lives. But her newest creation has the potential to be manipulated to kill a single person, as well as launch a global pandemic if it ever landed in the wrong hands. And unfortunately, someone knows what she’s created and will stop at nothing to get it. Piper's family hires someone to protect her when the threats become dangerous. Security specialist Aiden Creed knew all too well what someone would do to get their hands on Piper’s viral nanotech creation. His time in the British Army’s Special Air Service exposed him to the true evil that hid throughout the world. What he didn’t count on when he accepted this assignment was the danger Piper posed to his heart.

Parker Davies, former rodeo star turned U.S. Marshal, wants something he can’t have—Tilly Bradford. He had met the equestrian, fell for her, and then saw her name on a case that came across his desk. Suddenly he had to step back from the one woman he had wanted. Instead, he threw himself into the work of the task force he’d been assigned to—the one tasked with taking down the person responsible for financing the criminal underworld. Tilly Bradford wasn’t like the rest of her family. She didn’t care about the generations of old money, the glamorous galas, or being the center of attention. She cared about show jumping and investing in small businesses. And Tilly certainly didn’t ever care to see Parker Davies, the man who had completely shut her down, again. But then Parker went and kicked down her door. Handcuffs were used (and not in a fun way), bullets were flying, and criminals came out of the woodwork to take her out. Now it wasn’t just Tilly’s heart, but her life in Parker’s hands. The question was: what would he do with it, and would she even be alive to find out?

Kale Mueez just wants to work on his computer programs and, okay, some not-so-legal hacking. Even though he sold one of his computer software companies for more money than he’d ever need, he wasn’t one to sit back and do nothing. That is especially true since his father is a super soldier known around the world. After spending time in the army, Kale returns home to his small town of Keeneston, working to hunt down The Panther, the one elusive criminal that’s ever escaped Kale. Until a wrong number changed everything. Delaney Warner worked in military intelligence, so when she accidentally texted the wrong number about standing her up on a date, she felt silly.

When The Panther presents a threat, a wrong number turns into more than either Kale or Delaney ever imagined.

Landon Davies had worked hard to start his own restaurant. It was a very different path than most of his family had taken. He was one of the few family members that were not military or law enforcement. But his hard work had given him a restaurant that was beginning to take off when a woman’s scream in the alley outside his kitchen changed everything. Kate Ellington had scratched, clawed, and outright fought for where she was in life. She was the first female passing game coordinator in professional football. Some people thought that made her the team’s weak link and a perfect target for exploitation. But Kate refused to cheat, even if it put her life in danger. When Landon saved Kate in the alley, it didn’t just earn him a kiss. It earned him a target on his back. Now Landon isn’t just taking on restaurant critics, but the people looking to manipulate the sports betting world. As Landon and Kate take on these threats, they find their reputations, their lives, and their hearts are on the line.
