Fighting for Hailey by Katie Reus

She’s the one who got away…
They grew up together, dated for years—but when Jesse Lennox had a chance at a college scholarship and a new life, Hailey abruptly ended things. She wanted him to have the life he deserved, and with her track record knew she’d just bring him down. Now they’re both grown and she runs the new branch of Redemption Harbor Consulting, heading up their security division. But her past is about to collide with her present in a big way, and she can’t outrun her demons any longer.

This time, he’s playing for keeps…
Years ago Hailey joined the military and ruthlessly cut all her foster siblings out her life. Now that one of them is in danger she’s back—and Jesse isn’t letting her push him away ever again. One of their own has been kidnapped and with the clock ticking, they have no choice but to work together to find him before it’s too late. But the threat is much worse than they imagined. It will take all their combined skills—and breaking through Hailey’s walls— to unravel the clues in time to save him.
