Shifter

Mika is living in a world where light and dark are two extremes she can't pick between. Escaped from a government lab for "specials" or people with special abilities she meets Brynn, a selfless girl who lost her sister 3 months prior. She allows her to take her sister's place, gives her a home in her parents well to do mansion and from there things just keep getting more and more complicated. However she meets a dreamboat named Bobby, but maybe he is too perfect. Nothing is what it seems and choosing between light and dark is very difficult when all you've ever known is running.
