i think she most definetly should. There are so many other stories that could continue from breaking dawn. What happens with Leah, or what happens with renesmee. You know the Volturi will be back to mess with the cullens another fight with them would be interasting. Like i said there are many other misteries that could happen and probably produce more then just 1 book. So YES i do think Steph should continue the legacy we all sooo love!
