Loving Hard by Carina Wilder

After her engagement falls through, Riley needs to take a break from men, heartache, and well, everything. Heading to London during the rainy autumn season suits her mood perfectly. The last thing she expects is to meet a man who can awaken the feelings she’s locked away deep inside.
Always too eager to fall for the wrong woman, Galen Davies is on a hiatus from love. He’s sworn off relationships for the foreseeable future, sticking instead to his burgeoning career as a model. But when he gets called upon to take a stranger out for a night on the town, curiosity compels him to follow through.

After all, it’s just one night, and he’ll never see her again.
Or so they both think.
