While I loved all three books I have to say it left me wanting more... Rain deserved to find love, Candle (or Cantle) should have come back and Liir deserved some peace and happiness! Elphaba we needed more of her now that she came back for Glinda ( or did she)? This may be my longings but it wasn't the authors.
I felt the books sometimes to be a bit of a slow read but worth pushing through, I was never a huge fan of the true "wizard of Oz" but this made it so much more real and un child like which of course is the whole purpose of the true "wizard of Oz" movie and book. It made me think in a different way. We are all good and evil and sometimes what we think is evil is not nor is the good alway good.
