HEY! I'm going to be at Steamposium Seattle this weekend, so COME AND SEE ME! Buy my books! (I have so many books to sell please take them away from me)
Though it's a bit early chronologically, Abhaya and Elizabeth's father Edward Watson was based heavily on real life Edwardian explorer Percy Fawcett who vanished in the 1920s while searching for the mysterious city called "Z". If you ever feel like looking him up, his story is a fascinating one and his disappearance is still a mystery to this day!
