I love the Discworld series!

Hmm, how to describe them...*puts on thinking cap* They're basically comic fantasy. And they're kind of satirical, but you can read them as just humorous, too. Some of the main characters that come around a lot are Rincewind, a wizard who hates to be a hero or the main character in anything--he would much rather run away (he's the biggest coward

)--but he ends up stuck in the middle of things anyway; Sam Vimes, the commander of the police who's a very
good policeman--he doesn't stand up for all the politics and intrigue; Vetinari, the Patrician of Ankh-Morpork, basically the city leader and a very wily kind of person; Death, who's the living personification of...well...death

; Death of Rats, which is the same thing but for vermin--they're both interesting characters in how they view things; Susan, who is Death's daughter somehow and has some interesting other-worldly powers; the Witches, including Nanny Ogg, Granny Weatherwax, and Magrat Garlick--they can do magic, but it's never what anyone expects; and the Wizards, of whom Rincewind would belong to if he had any real magical talents whatsoever.
The stories kind of wander all over the place. Main conflicts usually occur with the Auditors, these beings that think that humans are way too "messy" and prefer to deal only in reality. There are also some conflicts with the Gods, who most definitely exist and like playing games with the characters as pawns.

I think my favorite book is either
Jingo or
Monstrous Regiment. I love all the twists that happen in that last book. Polly is a brilliant main character!
