Are All Your Books in the Same World?

Hello, Gordon Korman! It has been a while since I went to this forum but as I was reading “The Superteacher Project” I began to wonder something. Different authors like Rick Riordian have confirmed that all their books take place in the same universe and I began to wonder if it was the same for yours. Do all your books take place in the same universe? This would mean that you have basically created a universe where hypnotists, clones, ghosts, aliens, time travel, ETC exist. This sounded like a pretty cool idea even if you don’t want to make a crossover between your characters,(I asked you a while ago on this forum). Anyways, I decided that instead of just speculating on this idea, I might as well ask the author.

So what do you say? Do your books take place in the same universe or are they all in separate worlds?

Thanks,

Aiden
