Harry Potter and the Goblet of Fire

I think this is my favourite of the Harry Potter series to date - it's a bit darker and more interesting than the first three, while not being as depressing as I recall The Order of the Phoenix being (that's next on the reading list, because I've only heard it on audiobook, and don't remember it very well). The kids are very definitely teenagers now, but still manage to remain likable enough that they don't lose the reader's sympathy. Plus of course, the over-arching story of the return of Voldemort is really hotting up now!
