Harry Potter and the Goblet of Fire - J.K. Rowling

So much happens in this book and there are so many payoffs from things that have happened in previous books that it's one of my favorites to reread, even though there are many sad and dark parts. It's so hard to realize that there are no more upcoming books in this series, that I will never again read a Harry Potter book for the first time. The only real consolation is that some of my favorite moments in the books are in the next books in the series, so there is that to look forward to!
