Cristiana DiPietro

Years ago, Dirk Longstreet walked away from The Circuit, the merciless underground fight club with no rules, where money changes hands as men are killed. But now gangsters have got his brother, and only one more journey inside the ring will save his life.

A man awakens in an empty house that he is unable to leave. Battling fatigue, injury and amnesia, and guided only by a cryptic voice on his phone, he begins piecing together fractured memories of the events that led him to be trapped. With a terrifying presence confining him inside the house, he ultimately discovers a truth more horrifying than he could have ever imagined.
