By far this year this is my favorite series. It's packed with emotional turns and suspenseful moments that will make be on the edge of your seat wanting to read more and more.
More than 450 million copy's of Harry Potter have been sold. Harry Potter book's are sold almost everywhere.
Probably some of the best moments are during quidditch games with suspenseful moments and tight turns. If you want to learn about quidditch or more you'll have to read the book and find out your self and you might find your self stuck in a series for a while.
