Little Snow White (Re-imagined Breaking Dawn)

Bella was pregnant, that's what the Cullen's definetly knew for sure. But what they didn't know was that she was pregnant with twins. This had the family in shock, and in the end, Bella and Edward named one Renesmee, while Esme named the smaller one Stella-Maris (latin for "north star"). Maris' parents weren't very fond of her; in fact, Edward thought she was a demon and curse upon the family due to her dark abilities and difference in appearance. So when the Volturi find out about little Maris, what will she do? What will the Volturi do? And most importantly.....What will her family do?
