I read that there is a new sub-genre on the romance /historical fiction scene.
This one is called Romantasy. It first appeared in 2023. Some say the genre appeals to those who grew up with Harry Potter - young adult fantasy - and want similar fantasy elements but with sex and romance thrown in.
All the core tropes for romance feature in romantasy and the main plot focus is romance but the setting is some imaginative world often with mythical creatures and epic quests. It should tempt all those who like dragons...but you need a vivid imagination for this kind of thing.
I guess the Regency purist readers will avoid it like the plague and so for them can I recommend my latest offering - definitely no mythical creatures, but lots of romance! in The Duke & Two Sisters.
