There are plenty of good authors of juvenile fiction. No reason to put up with JK's nonsense.
Off the top of my head, alternatives to the Harry Potter franchise
The Young Magicians And The Thieves' Almanac by Nick Mohammed;
The Worst Witch by Jill Murphy;
Electrigirl by Jo Cotterill;
Unleashed by Ali Sparkes;
The Lie Tree by Frances Hardinge;
Akata by Nnedi Okorafor;
Legacy of Orisha by Tomi Adeyemi
