This is volume 1, where the beginning of the new story starts with Roxas, generally focusing on him and life with his friends. If you are looking for some Sora, Donald, Goofy in this book, there sadl isn't much mention of him, yet. If you have played the KHII game then you would know this. Nonetheless, if you are a KH fan, like me, you would buy the manga anyway. The artwork and how Shiro Amano portrays the game in manga form is still great with the same storyline, adventures and occasional quirk here and there. Another thing to mention is that you read this in the traditional Japanese right to left style, which can easily gotten used to. One of the most appealing things about this particualr book is the front cover, the coloured artwork is a visual treat to see.
I bought this from AmazonUK because it is relativly cheap, the UK rrp is £6.99, but i ordered with other items for free delivery.
