That's REALLY Weird!

I just found my not-yet-released book on Amazon! That was a very weird moment, but quite exhilarating! I won't be released until July, but seeing my cover right there with the Amazon banner was so cool! It's on the Amazon.ca and Amazon.uk sites, but not Amazon.com. I have no idea why. It's also on Overstock.com with a decent description of it. Amazon says it is #485,305 on the bestseller list, which amuses me since it hasn't sold any copies yet.

Since Scholastic hasn't told me about any of this, I wonder where else it's available for preorder?
