Mark's Noble Quest by Katharine Campbell

This is a sequel to Rosaline's Curse which is a romantic comedy version of Sleeping Beauty where the 13th century young woman awakens in 2017. She encounters our modern world and Mark, a young man who is not only a nerd but also her true love. It's a lot of fun. Read that first. 

This novelette (longer than a short story and shorter than a novella) follows Mark as he tries to prove to Rosaline that he's just as brave as the guys back in the 1200s. That's not easy in 2024 but luckily a friendly fairy sends him on a quest to climb a volcano and recover a beautiful ring. While undergoing three trials. 

So it is a classic adventure set up. Except that this story is being told by Katharine Campbell which means it is charming, funny, and resonates with modern readers' lives. That's all while following the rules of such a fairytale. 

 This is highly satisfying and I only wish it were longer.
