Perpetua, a 19 year old girl from South London, says that she is God. She gathers a motley collection of followers and begins her travels, performing miracles and spreading her gospel of unconditional love along the way.
Her message provokes a strong and ultimately lethal reaction from Christianity's warring factions, politicians and journalists bent on profit instead of the truth. Her story is told by four people: Jack, a tabloid journalist; Claire, a social worker; Beth, a media student; and Damian, a theology graduate and Church House intern.
