Lies Between Us by Nikki Rose

After a steamy one-night stand leaves Alexis with a baby on the way, and no way to find the father, she’s forced to make the rash decision to marry the infatuated small-town police chief who promises her the safety and security she needs.
But safety is the last thing her new husband offers as their relationship gradually becomes violent. When the abuse reaches an all-time high, Alexis finally finds the courage to take her daughter and run. Determined to raise her daughter alone, Alexis leaves everything behind, until a freak accident brings her face to face with the same man she’d shared that heated night with two years before.
