SOLVED. Unknown Science fiction book. [s]

[Jacob]

Looking for a book my sister found in her 6th grade school library in 2012. Here's what we know about the book: It is a science fiction set on a floating landmass much like castle in the sky. The mass was created and launched into orbit(?) by a scientist who never wrote down his findings only number sequences that unlocked memories in his head. The land mass had a society built into it with three defined social classes. The elite class being at the top with it's kingly leader living close to a magnificent spring, a middle class in the middle which the spring either flowed into, or it's water was passed down in buckets by the elite class, and of course the lower class at the bottom where the exiled people lived amoungst giant centapiedes who ate the waste thrown down there. The book followed the adventures of two children from the middle class who at some point make the daring climb to the top of the mass. What was unique about the book is it was somewhat interactive, as it had a website where you could enter the numbers found in the book to access the memories of the scientist mentioned before. That's all I got I hope someone can find this title and hopefully the website is still up and running.
