Can someone plz explain Bree Tanner to me?

if u mean the book i havent read it.

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

o is it something più specific about the book o the character te don't get?
