He's hostage to his past. She has a secret that could destroy him. The past won't stay dead. Betrayal and death haunt former British Special Air Service captain Lachlan Mackay after a disastrous mission in the mountains of Afghanistan ends his military career. Now a civilian, his job overseeing security teams in Kabul brings the opportunity to topple a powerful warlord, avenge the dead, and free himself from the crushing guilt of trusting the wrong woman. However, his plans for revenge get derailed when someone from his past targets his beautiful new American colleague. Sophia Russo wants to make a difference in the lives of the Afghan people. As the new director of Legislative Affairs at Landry Associates International, her job is to lobby Congress to support her company's development projects in the war-torn country. But when her best friend's father, a retired four-star admiral, tells her someone may be trafficking weapons to a warlord, she agrees to spy on the prime suspect, LAI's head of Global Security. Lachlan Mackay is dangerously sexy and full of secrets, but after getting to know the Hot Scot, her heart refuses to believe he's a criminal. When Sophia is caught in a deadly game of cat and mouse between Lachlan and an unknown enemy, she teams up with him to help prove his innocence. The tables are turned when their hunt for the truth makes them the hunted. To save Lachlan, Sophia may have to betray him, and Lachlan is forced to do the one thing he swore he'd never do again. Trust a woman with his life.

A need for justice she can't ignore. A need to protect he can't deny. An enemy out to destroy them both. Foreign service officer Emily Dane has never backed down from danger. But when she risks everything to free two girls from a sex-trafficking ring in Paris, she lands in the crosshairs of a ruthless crime lord. Now the hunter has become the hunted. Her only hope of survival? The one man she swore she'd never let get close to her again. Former Navy SEAL Nathan Long hasn't forgotten the night Emily walked into his arms-or how she walked out the next morning without so much as a goodbye. When she vanishes, he'll stop at nothing to bring her home. Protecting her is his mission. Wanting her again is the complication he can't resist. As bullets fly and tempers flare, Emily and Nathan must learn to trust each other before the enemy closes in. But giving in to their need could cost them more than their hearts… it could cost them their lives.

She broke his heart. Now he's the only man who can save her. Ryder Montague, future Earl of Cannington, was ready to sacrifice his title and family legacy for his American love, Nathalie Williams. But her sudden rejection on the eve of their Oxford graduation shattered him and the future he thought they'd share. Eight years later, Ryder is a hardened ex-SAS soldier and head of executive protection at Dìleas Security Agency. He thought he'd buried his love for Nathalie, until a new assignment brings her back into his life. Nathalie gave up Ryder-and her own happiness-to pursue her father's dream of creating a safer combat jet after her brother's death. Now, her groundbreaking AI software has made her a target. The last thing she expects is to find Ryder as her bodyguard. He's no longer the shy boy she loved but a dangerous man who still owns her heart. As threats close in, secrets and old wounds collide. Can Ryder and Nathalie trust each other with their lives-and their hearts-or will this be their ultimate Missed Opportunity?

He wants revenge. She's the bait. Can they work together to bring down a common enemy? Or will they make a Fatal Misstep? After a lethal street drug claims his mother's life, former Green Beret Caleb Varella returns to Arizona to honor her final wish. But the scars of his childhood still haunt him. Once she's buried, he plans to cut ties with his past and never return. His exit plan falls apart when he rescues a woman from a violent abduction. Gianna Barone is keeping a perilous secret and trying to stay one step ahead of the drug lord determined to get her back. She's rebuilding her life among the Navajo, using her skills as a doctor to help her adopted community. Her new protector is both danger and temptation, and the chemistry between them shakes her already fragile world. Caleb suspects Gia knows more than she admits. And when he learns she's fleeing the man he holds responsible for his mother's death, he makes a brutal choice: use her to draw out the enemy. But the deeper he gets, the harder it is to separate duty from desire. Love might not be enough to save them as threats close in, and trust becomes the deadliest risk of all. To stop a killer, Caleb must face the past he tried to bury-and fight for the woman who could be his future. Fatal Misstep is book four in C.S.
