Oh, yeah. Definitely, definitely yeah. For one thing - this is the book that inspired me to take up fanfiction, which taught me how to write, and spurned my great ambition to Be An Author.
Try to avoid spoilers, if you can, the Big Twist is pretty good.
OK, got Chamber of Secrets. Remember I work in the library, basically? ;-) Comes in handy at times! So...I'll get caught up, if slowly.
