Breaking dawn isn't my favorite. I like eclipse more. When I read breaking dawn it was very interesting and weird. The imprinting on Renesmee kinda ruined it.
Even though it's the last book in the series,it is my Favorit because Edward and Bella get married,have a honeymoon and after the birth of Renesmee,Bella at long last gets what she's always wanted: to be a vampire.So those are the reasons why BD is my fave.But I will be very sad to see it end in 4 months.
