Diana Wynne Jones writes fantasy. Many will tell you that her
     books are for children, but they are really for anyone who is
     interested in hearing about their favorite stories and cliches
     twisted into hilariously funny stories, or even people who want
     to see a 'new' outlook in fantasy.

      DWJ grew up in England and was moved many times in her
     childhood due to the unpredicatbility of bomb raids by the
     Nazis in WWII. Her neglected childhood and disorientation in
     family as a child show in many of her books.

      In college, DWJ attended lectures from both C.S. Lewis and
     J.R.R. Tolkien. This may explain the parallels between her books
     and theirs, although in reality almost all modern fantasy is
     based on the works of those two authors.

      Diana's books tend to focus on the power that weak people gain
     with better communication. In addition, parody runs strongly
     through nearly all her plots. Both lend to make a fresh and
     exciting story.

      I have chosen to divide the novels in my lists into two
     categories: Ones that take place in a single reality or universe,
     and ones that take place in more than one reality or universe.
     These do admittedly cross over often, but I have tried my best to
     keep it accurate.
