It looks like Amy and Dan are going to come to Australia in book 6!!! Patrick Carman said on the live interview.
They come to Australia to the Tomas Strong Hold where i believe Dan finds out he's a Tomas.
And in the next book, book 7, it sounds like they stay in Australia a little longer...
What i still dont get is if they get 1 clue every book how are they going to get 39 in 10 books???
If anyone has and help or hints comment or email me and it might go onto the blog!!!
