He’s a protector with nothing left to lose. She’s a survivor with everything to fear. Together, they’re a target.

Callum Hale doesn’t do second chances. A former Army Ranger cast out for breaking orders, he’s built his new life protecting clients who can’t protect themselves. But when he’s assigned to Grace Willoughby—a quiet illustrator hiding from the abusive ex-husband who refuses to let her go—Callum’s ironclad control fractures. Protecting her isn’t just a mission. It’s personal.

Grace has rebuilt her life from the ashes, but safety has always been an illusion. The closer she gets to Callum, her older brother's best friend, the more she realizes he’s not just a shield against her past—he’s the first man she dares to trust. And the one man she can’t afford to lose.

When a brutal abduction shatters their fragile peace, Callum races against the clock to track Grace’s captors. Enemies circle closer, secrets inside Titan threaten to explode, and Callum must decide how much of his heart he’s willing to risk. Because falling for Grace may be the one line of duty that costs them both everything.

Perfect for fans of military romance, this pulse-pounding romantic suspense launches Cristin Harber’s brand-new Titan Protectors series—where loyalty is unbreakable, love is dangerous, and trust is the ultimate risk.
