Star-crossed lovers...

Driven by her traumatic past, Nadia Bishop has dedicated her life to helping children orphaned by war around the globe. She won't let anything stand in her way—not even the sexy former soldier she left back in the U.S. As one of the most experienced workers in her relief organization, she's their top choice to send to Kabul as the security situation in Afghanistan teeters on the verge of collapse. She's helping get children to safety when Callum shows up unexpectedly, igniting an intense longing that makes her question the life she thought she wanted. Then things suddenly spin out of control, and Nadia is forced to make an impossible choice. Now there's no turning back. Nowhere to run. And her only chance at survival is the man she's been trying not to fall in love with.

...are about to face the maelstrom of war together.

Former Delta operator Callum Falconer had his fill of combat. Now a highly skilled and respected security contractor, he gets to call the shots and choose the jobs he takes. So when a contract comes up in Kabul, a place he hoped never to see again, he volunteers to lead the security detail for one reason: Nadia. She changed his whole world when they met, making him feel things he never thought possible. Yet the more he wants to hold onto her, the farther she slips out of reach. Then things turn deadly, and nothing else matters but her safety. With Nadia's life in imminent danger there's nothing he won't risk, and no rule he won't break to get her out alive.
