@turbodragon one of my favorite fantasy series is The Belgariad by David Eddings: https://en.wikipedia.org/wiki/The_Belgariad

it's a little bit typical fantasy but it's a fun read. the characters were the strongest draw for me, and i read this one around the same time as i was reading HP

most recently in recs i've been shoving at everyone, NK Jemisin just released the third book in her Broken Earth trilogy, the first one is called The Fifth Season: https://en.wikipedia.org/wiki/The_Fifth_Season_(novel)

more dense and weighty but all three books are fantastic. you get awesome concepts like geology magic and it gives you a lot to think about
