Stella recommends Role Playing by Cathy Yardley

A different kind of romance novel featuring middle-aged protagonists who are still learning about themselves. Thoughtfully written to include a demisexual hero and a lot of online gaming.
Role Playing is a great book if you're looking for diversity in a romance.
