All That Lies Between Us by Amanda Cuff

Happily engaged. Fulfilled by a lucrative career. Addison McCormick thought she had it all—until she caught her soon-to-be-husband cheating.
Forced to start anew, Addison decides a vacation is just what she needs to escape the wreckage of her life in LA, and serene Colorado is calling her name.
What she doesn’t expect to find is Chase Prescott: the sexy, brooding neighbor at the cabin she’s renting. She sees him as nothing more than a vacation boyfriend, a quick and dirty fling to help her get over her recent heartbreak.
But when that spontaneity leads to the surprise of her life, Addison discovers that Chase’s mysterious allure isn’t just a front, and that he has a secret that will change everything.
What happens when the fantasy they created crashes head-on with their harsh reality? Can Addison find her new place in a world she might not be welcomed?
