I've always wanted to read the Harry Potter books but I've never gotten around to it. Are they good?

The books themselves sold 500 million copies worldwide. That made them the best selling book series in history. I enjoyed them too! I also liked the movies quite a lot.

Wow that's a lot! So what is the Harry Potter series about?
1_Wizard
It's about a wizard and his friends. They struggle against an evil wizard named Voldemort who wants to overthrow the wizard government. Harry, the main character almost died to this evil wizard himself as a baby!

That does sound like something I'd like to read! How many books were in the series?
