It’s never too late to write a bestseller (or two).  Marina Lewycka talks about publishing her first novel, The Short History of Tractors in Ukrainian, at the age of 57.  The book went on to sell a million copies in more than 30 languages and win several awards. Her second novel, Two Caravans, was short-listed for the George Orwell prize for political writing.  She is currently working on her third novel, We Are All Made of Glue.
