Deep under the earth, Grant Borrows has supposedly fallen to his doom. But when something crawls out of that pit-something dark and merciless with unrestrained power-it proclaims itself 'Oblivion' and begins moulding the planet into a twisted, barren, dangerous world. A Dark World. Is it Grant Borrows, returned from the dead? Or something more sinister-something no human ever imagined possible? As Grant's remaining friends finally learn the ultimate truth behind the events that have shaped their lives, they secretly gather for one last battle.
