Hehe, it was really interesting while reading this. I have the feeling that I was a Hogwarts student reading a school library book, in which many Harry Potter Big Fans would probably imagine themselves to be at Hogwarts while reading Harry Potter books. 
 Now, Fantastic Beasts and Where to Find Them did provide a great deal information about beasts that live in the Magical Community, and once more shown the detailed and imaginative thinking of J.K.Rowling. She provided many appealing creatures, description and origination and all, plus the danger level. 
 Even though it is not a story, it is a good documentary-guide book for those who want to examine the Wizarding World.
