Relinquish by Noelle Adams

She was supposed to be taking a break from work to rethink her future. She wasn’t supposed to be falling in love with her boss.
He was supposed to be resting at a beachside retreat and unwinding from the stress of his job. He wasn’t supposed to be wanting her in ways that had nothing to do with the job.

Betsy has worked with John Davenport for four years, and she’s always been an efficient, practical member of his crisis response team. He might be brilliant, attractive, and good-hearted, but he’s also driven, rather grumpy, and emotionally unavailable. Plus, he’s never looked at her with any interest other than a friend and co-worker. No one has ever really been interested in her. She’s never been the kind of woman that men fall for.

No matter how much she loves her job with an international relief organization, she knows she can’t do it forever. But as soon as she begins thinking toward a different future, John starts to respond to her in a completely new way.
Maybe it’s just a temporary feeling, prompted by some much needed downtime. Or maybe they’ve had more in their hearts than they’ve ever admitted.
