This was a great read.
The best part of the book was the battle between Jibril and blank, and that probably is my favorite battle in the series so far. The description, the whimsical characters, Sora and Shiro's amazing chemistry was a breeze to read. This book is a fantastic, easy read.
The reason I gave this four stars and not five is because this book only has one major battle. Furthermore, this book ends in a cliffhanger, which I am not too much of a fan (this is merely a personal opinion). Had this book included any other major battle or had it been paced a little better (I found this book slower than the first volume), I would have given it five stars.
Read this book, you will not regret it.
