Honor-Bound Lawman by Danica Favorite

Her rancher bodyguard...

When Laura Booth's dangerous ex–husband escapes from prison, she turns to the one man who can protect her: Owen Hamilton. Living with the widowed former lawman – who once helped put her ex in jail – and his adorable twin daughters on their Colorado ranch is a welcome respite. For the first time, Laura feels safe – but after her troubled past, she'll never trust her heart again.

Owen would like to say only obligation draws him to Laura's side. But in his gut he knows his feelings for the gentle beauty run deeper than duty – and it stops him cold. After guarding their wary hearts for years, can Owen and Laura give love a second chance?
