Few contemporary novels will have had a year like Milkman by Anna Burns. It was published, without a great deal of fanfare or advance publicity, in May 2018. But then it began to attract attention by dint of being longlisted, and then shortlisted for the Man Booker Prize. Some were surprised when it won. I wasn’t. In the course of a long commute to work, I had listened to the remarkable audiobook of Milkman twice.
