Heads by David Osborn
The was a surprising fun read. I liked the ideas and kind of reminded me of the movie with Steve Martin's The Man with Two Brains - but in a scary way of course :)
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.
