Fantastic Beasts and Where to Find Them
This was one of two books written for Comedy Relief a non-profit organization that uses humor to heal. J.K. Rowling donated all her proceeds (yup 100% but we knew that she is that kind) from the sales of this book to the charity.
Synopsis
This is one of Harry's textbooks, and so besides being informative, it's also humerous as we get to see all the pictures and graffitti he and his buddies have written in the book. It's a little like an encyclopedia of magical creatures, so it's really fun to read! We get some insight on some of the creatures that Rowling has introduced us to thus far, and we get to speculate on some of their natures (is Crookshanks an animagus or half kneazle?) It's really great fun, and we get a note from Dumbledore in it as well!
