Chasing Shadows, Book 3 by Catherine Bybee

Avery Grant doesn't date. Her first marriage was a mutually beneficial contract that gave her the financial freedom she needed to step away from her controlling parents. Wealthy and single, the last thing she's looking for is love sneaking in to mess up her life plans. And after a brutal attack, she's determined to never be vulnerable again, even if the new man in her life helps her feel safe.
