Fantasy book recs w/characters aged 25+??

I turn 30 next year and I love Sci-Fi/Fantasy/Romantasy books, spice or no spice I enjoy them. But why are all the characters always babies? Like for instance I love ACOTAR and am currently in the middle of ACOWAR but honestly I relate more to Mor's character than Feyre. Feyre has has very little life experience beyond surviving and hunting (and any other horrors regarding her childhood I might have yet to uncover) and what she experienced UTM and in ACOMAF. And no hate to her character for that I do love her character and the growth she has had since the beginning of ACOTAR. But Feyre is literally I think 19/20?

Fantastical things can still happen when you are older, so I would LOVE some recs for books that have 25-35ish year old characters. Excluding like GOT and LOTR since I already know about those 🙂 Thank-you to anyone who has some!
