She's chasing the truth. He's trying to save her from it. 
 Some secrets are meant to stay buried. Millie Marsh should have learned that the day her dad died, protecting her from a past he didn't want her to uncover. But walking away has never been her strength.  
 Now a CIA operative, Millie's on a mission of her own: find the truth—no matter how dangerous it gets. And it's about to get deadly, because the answers she needs will lead her straight into the heart of one of the world's most lethal terrorist networks.  
 Enter Navy SEAL Mason Davis. His mission: keep Millie alive. His reality: survive her. She doesn't follow his orders. She doesn't trust him. And she's hiding something—something big enough to get them killed, which is a problem. Because Mason doesn't break rules and he doesn't get involved. Until her… 
 As the mission plunges deeper into a world of lies and betrayal, the tension between them ignites into something neither of them can control. And just as Millie's about to get the answers she's been chasing for eight years… everything changes. Because now she has a choice: find out who she really is or walk away from the truth for the only man who's ever made her want to stop chasing it.
