The first Enders novel is amazingly well written and plotted out. After the first, it is a slow, long decline by the next 2 books into averageness. Has been a long while since I have read them, but really remember not liking the next 2 all that much.
You are not your magic weapon and armor. You are not your spell buffs. You are not how much gold you have, or how many times you've been raised from the dead. When a Big Bad Demon snaps your sword in two, you do not cry because that was your holy avenger. You leap onto its back, climb up to its head, and punch it in the eye, then get a new damn sword off of the next humanoid you headbutt to death.
