After escaping the servitude he suffered while being imprisoned in heaven, Apius—an ancient evil entity—calls out to Peter Nichols from beyond the grave. It was this “child” who thwarted Apius’s plan for revenge as he sought out the destruction of humanity for the last several centuries. But Peter now owes Apius a blood-debt. Collecting on this debt, Apius captures the soul of Peter’s mother, hoping to draw him near. Once he rids himself of Peter, he can then move to release his brothers from their guarded sarcophaguses and wipe away the scourge of mankind.

However, fifteen-year-old Peter will not make it easy for him. After he discovers a hidden symbol, a series of events brings Peter back to heaven where his three lives converge. Besides freeing his mother, Peter has seven days in which he must locate and defeat Apius if he is to help prevent the apocalypse.
