Evil Twin - Tenebrosities, #1

A haunting tale of a monster who lived inside mirrors, and the ghost he left behind when he died. What would you do to get rid of an abusive ghost? When Michael's father died, he left behind a grown-up family shattered by years of his broken, abusive, alcoholic behavior-and a legion of adoring fans who hung on every word of his stories. They called him creative. But the truth was that Michael's father had the ability to violate the boundary between one side of the mirror and the other, traveling between reflections and watching, and interfering, with other people's private lives until there was little of the man left-only a monster. Now the man is dead.
But part of the monster has been left behind.
