so i'm re-reading The end of Oz, and I noticed it a while ago that DMD is red, TWWR is green, YBW is blue, and EoO is yellow. with that being said, i think there should be a fifth book because not only did Danielle leave the door wide open at the end of EoO, she also used three colors of Oz not counting green for the Emerald City. the fourth color is purple, so why would she leave it out? but that's just what i think lol
Hmmm very interesting, I never noticed that before!!! But the end of EoO does leave the door open for another book, and a lot of people suspect that she'll write another one! :)
