Fictions about Witches / Pagans wanted

I'm after suggestions for my Mum, singular books are fine, trilogies/collections are preferred.

She's not a witch but she loves all things witchy, wiccan, pagan… that sort of thing.

Are there any fictions out there that would be suitable?

Nothing too modern, more along the lines of traditional old-timey 15th-18th century settings where they had real witch hunts etc, anything to do with covens, spells etc.

Nothing too gorey, some romance would be good… nothing too dark or depressing.

I don't know if I'm asking for too much lol

Thanks
