The Life Of The Little Swan

Isabella Marie Swan and Evelyn Vanessa Dwyer-Swan are half-sisters who come to live in Forks, Washington for their own reasons. We already know Isabella's story, but what role does Evelyn play in all of this? This is the Twilight series and beyond in the little sister's POV.
Adapted from the biggest and best-selling novel, now a major production series, this is a fanfiction of The Twilight Saga.
P.S -- The plot and the characters are owned by Stephanie Meyer, and none by me. Also I want to acknowledge Thornton CN, i have loved and cherished her series.... Thanks to both these authors.
