Book Review: Rising sun

As many of you have already heard, has Stephenie Meyer published a new book named "Rising Sun".
The book is about Bree Tenner who is mentioned in the 3rd part of the Twilight Saga Eclipse.
She is a part of the vampire army that Victoria has created to revenge James who has once been her mate.
Bree Tenner thinks that she can't go out at day because someone made her believe she couldn't resist sunlight. By the time, Bree gets to know that many rumors about being a vampire are not true and especially that her creator has lied to her and her new friend Diego.
Together, the two of them, are trying to find out why Victoria is creating a big army of vampires to protect herself from one of her enemies.
Bree finds out that they're not the only vampires in the area.
For some reason the Volturi find out about Victoria's plan and so they came there to do what they have to do and to abide the rules.
Bree is a big part of a war that they can not win.
As the only vampire who's ever getting the chanche to face Bella, she would have survived if the Volturi weren't involved in that.
But Bree dies at the end of the book which I knew before I read "rising sun".

Rising sun is a book that you don't have to read to make up the actual Twilight story which is based on the lovestory between Edward and Bella.
It is more like an addition to the novel that gives you backround information.
If they're necessary you can decide for yourself.
Rising Sun is written in simple English and the information about Bree and her army are short and simple.
I personally think Bree is telling us her story in a compleatly different way than Bella does.
At the begging you may have your problems but if you keep reading the book gives you a lot of information you wouldn't have expected before.
Although I actually liked the book, to me Twilight still concerns Bella and Edward and their never ending love story .
What do I need a book for that does not even is about the actual reason why I like Twilight so much?
It's cool to get to know more about this crazy and mysterious world of vampires buuuut for the price of 15 euro? i'm not sure if this is a little unecessary.
I would have better liked an official version of Midnight sun which is the first Twilight book from Edwards view.
The book was written to make some more money.. or well maybe not written for this reason but published.
Don't get influenced by my point of view. Buy the book and form your own opinion :)
