More info would help, but I'd start with Rithmatist, Emperor's Soul, Steelheart
or Warbreaker.
Mistborn might also be good for you, but I'd want to know more about other fantasy books you like.
Rithmatist is like Harry Potter
Steelheart is somewhat in the vibe of Ready Player One
Emperor's Soul is a short novella that won the Hugo, so it's a good one.
