Harry Potter - Official Thread 2!

[Cassie]

It's a very big one to start off with you know. Biggest one of the series by far. That's the only reason I didn't suggest it. It depends what you're after...

OotP = plot development
HBP = character development.

OotP is more dark and angsty, HBP is lighter.

Have you read all the other books beforehand though? Otherwise it's not going to make sense at all, no matter which book you choose.
