This was the review I posted back in 2008 when I first read this book:
I love these little side books, this one and the two Hogwarts text books that came before. They're great fun to read and really add to the illusion of a 'real' magical world.
This book consists of five tales, the magical equivalent of Muggle fairy tales. All five are charming--a couple are quite dark--albeit quick reads, but in my opinion very satisfying.
I enjoyed reading Dumbledore's notes at the end of each tale along with the footnotes added by JKR.
