The unique friendship between an angel and a human is the only hope for the future — but can they remain friends?It’s one thousand years since medical scientists brought a dead brain back to consciousness. When they discovered the reality of life after death, they laid claim to Heaven and set off a war against the angels.Now the Earth is a ruined wasteland. Descendants of the original scientists continue the war with their armies of artificially created Humen. When the greatest of Doctors, the all-knowing Doctor Saniette, takes control of the Bankstown Camp, the fighting moves to a terrible new phase.Miriael is the angel who fell to Earth, ate mortal food and can no longer return to Heaven. Ferren is the young tribesman who has been her only friend since her own kind abandoned her. Together, they work to unite the tribes in an alliance independent of the Humen.But suddenly Miriael has another friend. A beautiful, caring angel visits her in secret and offers her what she most desires: the chance to return to Heaven. The consequences will be extreme … for her, for Ferren, for the world.
