Kiss Me, Doc by Devon Atwood

Ruth Coldwell is the world’s worst matchmaker.
The truth is, she’s a total fraud. She knows nothing about love and even less about actual relationships. But if she can’t convince her boss that she’s a competent matchmaker, Ruth will end up right where she startedーa jobless, hopeless woman with a random doctorate and a broken heart. Her new job as a matchmaker is in danger of imploding, so Ruth does the only thing she can think to do… she claims to have a husband.

Callum Reed just found a fake wife.

When Cal shows up to a speed dating event with the express purpose of reaming out Dr. Ruth Coldwell for her abysmal matchmaking skills, he finds himself with an unusual opportunity instead–she needs a fake husband. He needs a fake girlfriend. It sounds like a match made in heaven, and he proposes a deal. Fake date him, and he’ll fake marry her, and both their problems will be solved.

As the lines between fake dating and real love begin to blur, a sinister shadow from Ruth’s past emerges, bringing with him a painful reminder. Ruth was never meant for love. And Cal was never meant to be hers.
