As Dark As Ebony

Ebony isn't normal and she knows it. But the only other person who knows is her big sister Saffron. No one else can find out. That's crucial.

She never knew her parents. They left when Saffron turned five years old and Ebony was one, leaving them in care of older brother Peter. But he left too, after seven years. That was when Saffron decided to tell Ebony what she was capable of.
