The clock is ticking and the survival game can no longer be stopped. James and Chloe have been chosen and nothing will ever be the same again after discovering the Dark Unknown.

"It is said that our worst fears come from within. But... What if there were a greater fear than we are capable of conceiving? What if that terror were much closer than we think? Suffering is the only way. Fear is a necessary evil."

What kind of curse does the Beresford mansion keep inside? For 200 years its inhabitants have suffered the consequences of an unknown shadow, a dark being who walks among us, and whose existence extends beyond what we imagine.

Now James and Chloe will face the ultimate test of their lives. They will know the true horror. The suffering of a father. The despair of a daughter. The clock is ticking and the survival game can no longer be stopped.
