That morning, Jim Sams, clever but by no means profound, woke from uneasy dreams to find himself transformed into a gigantic creature.Jim has undergone a metamorphosis. In his previous life he was ignored or loathed, but in his new incarnation he is the most powerful man in Britain - and it is his mission to carry out the will of the people. Nothing must get in his way: not the opposition, nor the dissenters within his own party. Not even the rules of parliamentary democracy. Ian McEwan pays tribute to Franz Kafka's most famous work to engage with a world turned on its head.
