More shocking than Coma, more terrifying than The Terminal Man, Heads is a thriller that goes deeper into the horrifying future of medicine than any novel has dared to go before. In an ultimate step into terror, David Osborn explores the murky boundaries between volunteer and victim, ambition and ruthlessness, life and death, when what begins as highly-classified research by a team of responsible doctors ends as a deadly game in which any of the players can be condemned to a purgatory more ghastly than hell.
