I started reading the Harry Potter series when the third or fourth book came out and then always bought the newest one and read it right away. So it has been years. As there is a Buddy read for the series right now I decided why not. I have wanted to reread them some time anyway so now I have even more Motivation. 
 To book 1: You can see that it is written primarily for children. It is not as violent or complex as the later books. But I really loved being introduced and submerging myself in this world of Hogwarts once again. It is like being back at a favourite vacation spot. Everything feels so well-known and comfortable. I love the atmosphere, the initial glimpses you get into the world of Magic, Hogwarts, friendships and the potential return of you-know-who.
