On Reddit, u/1-2-switch suggested The Abhorsen series by Garth Nix. This YA Fantasy series follows Sabriel, a teen who must become the Abhorsen in order to protect the Old Kingdom from the return of an evil entity known as Kerrigor.
u/GayFemboyOmniNerd responded, “Conan by Robert E. Howard! Those stories are amazing. J.R.R. Tolkien himself loved them and took inspiration from them.”
“They inspired modern fantasy including DnD about as much as Tolkien's work did.”
