ShadowSpark Hooves is a young mare with a life one would not speak of. A life filled with abuse, drugs, alcohol, and neglect. Her heart has been torn to shreds from years of pain. She is certain everyone–and everything– is out to hurt her and her family, which has been now reduced to her and her little foal sister, GloomGlimmer. Until, she meets a fiery-spirited pony known as Speedster Dash, who will stop at nothing to heal her ruined heart.
