I already finished The short detik life of Bree Tanner! Who too? How do anda like it?

I loved the book. I am a big fan of backgroundstorys. In this case, ecpecially the Volturi-background in this story, and how Stephenie Mayer let this book influence the Eclipse movie. In TssloBT she even managed to introduce a new character, that might someday reappear in the Twilight universe.
Sory for that little spoiler, but this has to be berkata too: Rest in peace Bree and Diego...
