I have a few recommendations!
Throne of Glass series by Sarah J. Maas is excellent, there's a lot of world building and complex characters. Plus super awesome, varied, diverse female leads from the get go! The main character, Celaena, is awesome, and Princess Nehemia is incredible (and my fav). And that's just the first book. It starts off a bit love triangle-y in the first one, but by the second that's preeeeeettty much done with so take that as you will. Currently, up to the fourth book has been published, I *think* the fifth comes out in September?
Air Awakens is another female lead fantasy, this one's by Elise Kova. Think Avatar the Last Airbender meets high fantasy. Elemental magic plays a big role in this one, and the fourth book out of five comes out later this month, and the fifth in July!
Both do get into some adult themes, but they are still young adult. I'd say pg-13.
If you are at all into fairy tale retellings (I'm working on a big thesis about these so I have a LOT of recommendations), I suggest Entwined, a version of the 12 dancing princesses by Heather Dixon.
Or, for another, but still very different, version of the same story, Princess of the Midnight Ball by Jessica Day George was excellent and had two very fun sequels, Princess of Glass and Princess of the Silver Wood, retellings of Cinderella and Little Red Riding hood, respectively.
And then, for short, fluffy, and cute, K.M. Shea's Timeless Fairytale series is a nice set of short novels giving a variety of fairytales the YA treatment. They could all very easily be standalone, but there are details in each that connect them all. These are self published, however, so some of the editing is a bit off.
Hope those help!
