The Coven Princess (The Coven Series Book 1)

Your blood does not define you.
Harley Torrance's parents were killed in a home invasion when she was three. Adopted by a nice couple, Harley begins to develop strange powers. At fourteen she brews a potion so strong it gains the attention of the Coven King, and changes her world forever.
She's not human, she's a witch.
Now a part of the magical community, Harley must learn to control her powers lest the Darkness already in her blood overcomes her. Can she dampen her lust for power in order to stop the Dark from taking over the Coven and killing everyone in their way?
