I recommend The Magicians by Lev Grossman. It's a a short-ish fantasy novel that takes a more realistic look at it's own thinly disguised versions of (first) Harry Potter and (second) the Chronicles of Narnia, a bit like a more cynical flip-side to HPMoR. It's a great read if you don't mind something leaning a bit more pessimistic, but it's not without hope. It's also quite funny if you like dark, sometimes subtle humour.
