If you want magical girl stories, you may be better off looking for manga or comics. After 'Cardcaptor Sakura' firmly entrenched the idea of frilly costumes as essential to the genre, few magical girl novels have come around. "Solte the Traveler" is a rather fun shounen take on magical girls that I found on mangadex recently (bonus points for having an isekai'd character who is not the protagonist), but here on scribblehub I rarely see any, except for a few that are LGBTQ themed. The queer community has long been oddly taken with Sailor Moon after all. 'The Prism Girls and the Magic Mists' here was enjoyable, but perhaps a little philosophic for what many might expect from the genre (although if you pay attention there are some dark and complex themes in the aforementioned Lyrical Nanoha).
