The End of Harry Potter
I won't say anything about the plot or about the end because I don't want to spoil it, but I could not put the book down. I couldn't. I read all 749 pages in five hours. I could not stop reading. I stopped for 10 minutes to take a shower, but that was still in the beginning of the book.
I just... I literally wept during this book. I haven't done that since The Far Pavillions.
I'm glad it ended the way it did. It felt like the right way to end the book.
