I've been a fan of Harry Potter for most of my childhood - I basically grew up with Harry Potter. I know most of the books nearly off by heart, that's how many times I've read them.
I feel that the books are far better than the films - the books give more detail and you actually know what's going on. The movies are pretty vague and you don't have a narrator telling you what's happening.

Harry Potter and the Half-Blood Prince is the sixth book in the amazing Harry Potter series, written by JK Rowling. In the middle of the summer, Dumbledore comes to Privet Drive to collect Harry, to take him to the Burrow. The world, both magical and non-magical, is becoming unsafe for everyone to live in. Voldemort and his followers, the Death Eaters, are causing havoc and chaos in the world, and many people are dying because of him. It's Harry and Dumbledore's job to uncover Voldemort's secrets to find out where Voldemort has hidden his horcruxes. Near the end of the book, Harry and Dumbledore go to a secret cave where Dumbledore thinks Voldemort has hidden a horcrux. The horcrux, which is a locket necklace, is lying at the bottom of a basin full of potion. The only way to get the locket, is to drink the potion. Dumbledore drinks the potion and has horrible visions. Harry takes the locket and they escape from the Inferius which are closing in on them. Dumbledore very weak, they return to Hogwarts and fly onto the Astronomy tower on broomsticks, provided by Madam Rosmerta (the barmaid in The Three Broomsticks pub). The Death Eaters managed to get into Hogwarts, and soon they find Harry and Dumbledore on the tower. Dumbledore wordlessly immobilised Harry, and Draco disarmed him at the same time, with the Expelliarmus spell. Severus Snape comes, and kills Dumbledore.

I found this book really interesting, and I could read it for hours on end without getting bored. JK Rowling uses a lot of interesting and exciting words, and all the characters are very unique. I honestly don't know how JK Rowling came up with the concept of Harry Potter, but I must say that she must have a really good imagination to think everything up. Once again, JK Rowling has written yet another amazing book about Harry Potter's adventures, in such a breathtaking way.
