Guarding Bella by Kaylea Cross

Her past should have stayed buried.
Bella thought she could escape her past. For a while, she did. She even found happiness and the chance for a future she never thought possible. Until one day when it was all taken away in an instant, forcing her to leave behind the man she loved just to survive. Now her nightmare is finally over and she needs to reclaim everything she lost. Except she doesn’t know whether he’ll take her back. And she’s about to discover that the past won’t let her go so easily.

Now it’s coming after them both.
Professional bodyguard Creed’s whole world caved in the day Bella left without explanation. Now, over a year later she’s back without warning, and what she tells him leaves him reeling. She’s been through a hell far worse than he’d ever imagined, but one thing is certain. He will love her until he draws his last breath—and won’t let anything or anyone take her away from him ever again. But when deadly forces from her past life come for her, they find themselves in a fight for survival unlike anything they’ve faced before. And the only way out is to make an impossible choice that could tear them apart forever.
