HI Diadem fans! The big news for all of you is that book 11, "Book of Time" and book 12, "Book of Games" are now available from Amazon.
Meanwhile, "Diadem" has been published in several foreign countries, and I thought you might like to see how your favorite characters have been portrayed elsewhere!
Diadem was another of my creations for editor Craig Walker. He asked me if I could create books something like the computer game Myst. Now I'm probably the world's worst player of computer games, and I couldn't get very far when I tried to play it, so I simply went of and created something that seemed vaguely game-like. I had my characters make moves across planets instead of spaces on a board. This way I could give them completely new menaces to fight in each story.
Craig wanted to add puzzles to the books. These were all written by David Levithan, who was Craig's assistant at the time (and is now an editor and author). That's why the puzzles vanished after book 6 - I went to a different publisher, and there was no way I could match what David had done.
