*** I note if they are not Christian/clean.

Any Fairytale retelling by Melanie Dickerson -’Nuff said. I haven’t read any of her Regency books, but they’re probably good as well!
The Lunar Chronicles by Marissa Meyer (not Christian, fairly clean)-Her world-building was really unique, and I thought all of the characters held to their own personalities so well. -If you want my opinion on the ending, email me. We can discuss it!
Harry Potter by J.K. Rowling (Not Christian, fairly clean)-Seven books, eight movies, and several spinoff book and movies series. Need I say anything?
