Does anyone know a website where I can find the setting, characters (and so on) in a book called Cam's Quest?

http://www.amazon.com/Cams-Quest-Continuing-Nevermore-Apprentice/dp/1581960565/ref=sr_1_1?ie=UTF8&s=books&qid=1254079731&sr=1-1

This book is still in hardcover, which means it's so newly under copyright that it'll be a LONG time before you'll find summaries, analyses, etc., online for it.

Scroll down in the amazon.com link above to read some reviews. That's about the best you'll do, no doubt.
