Can someone plz explain Bree Tanner to me?

if u mean the book i havent read it.

The book - The Short một giây Life Of Bree Tanner? It's just a novella describing a thêm typical newborn vampire's existence, bởi giving the history of the newborn who'd surrrendered to the Cullens but was killed bởi the Volturi in the end of Eclipse.

hoặc is it something thêm specific about the book hoặc the character bạn don't get?
