Harry Potter and the sorcerer's stone (fantasy) by J.K.Rowling

As I mentioned that I was growing up with reading books for fun, I just managed to finally read Harry Potter 1 at the age of 25. Better late than never, right? This is a great book, and maybe you all know that already, but I enjoy getting lost in the fantasy world that J.K.Rowling described in the book. I'm curious if you all have a favorite book among the Harry Potter series that you want to share as well.
