I read this book last week and was completely illuminated!
So the second year of Hogwarts School of Witchcraft & Wizardry starts and the adventure starts from the very beginning.
The writing style of the book is very much like its predecessor except that it is a tad bit more mature ( Im not saying that the first one wasnt mature enough) .
The story goes ever deeper and the mystery unravels ever so slowly, but with every answer, new questions arise!
As in every book you cannot guess the ending, but be sure never does any part of the book disappoint you.
Once you decide to pick up the book, its hard to put it down. The plot is clean with many loose ends which are taken up in the next books.
If you have liked the spells in the first book and look forward to get to know more about them, then you will not be mistaken if you choose to pick this book up.
All in all, this book is worthy of being the successor to Harry Potter and the Philosophers Stone.
My Regards.
