my niblings are 5 and 6 respectively. they like to read and be read to and I would like to get some books to help foster their enjoyment of reading as they grow up - so ideally stuff that’s not too challenging but still good for fostering young imaginations. obviously sneaky subversive themes are welcome - the sneakier the better, I kinda suspect their dad leans chud.
I literally came to recommend A Wizard of Earthsea. I think it would maybe be a little hard for someone of that age to read on their own, but if an adult is reading it to them I think they’d love it.
Just don’t let Dad read the author’s notes, she’s pretty explicitly based in those.
