To be honest, I am not particularly writing for the book set, but it's availability as a product. The book is,of course, written fantastically but for readers who have read big books like those of Dan Brown and Archer without getting tired, well, they will find it VERY short. To be more precise, the books are even shorter than the Secret Seven books of Enid Blyton. So,if you look at it as a book that can keep you occupied for a long time, it is not a very reasonable price for the books are short.But if you are buying it as an addition to merchandise for fandom,well,then I think It's Okay. I bought it because I am a big Potterhead and the money will be going to 2 different charities. But still, the books are short for intense reading purposes.
