Franz Kafka wrote dark, terrifying stories. One is about an artist whose art is starvation. He starves himself to death. The most famous Kafka story is probably The Metamorphosis. It's about Gregor, a salesman who wakes up a cockroach -- at least that's usually how it gets translated. Insect Gregor gradually loses connection with everything that human Gregor knew and loved. His wants to die, and he does. This is the story that Matthue Roth has reworked into the centrepiece of his new book for children. It's called My First Kafka: Runaways, Rodents and Giant Bugs.
