Naomi Ishiguro began writing Common Groundin the aftermath of the Brexit referendum. The title refers to both Goshawk Common in Newford, Surrey, where 13-year-old Stanley Gower meets 16-year-old Charlie Wells, and the threads that bind the boys despite their differences. Stan isn’t a talker; he tends ‘to stay quiet and stare at people’, which, together with his second-hand clothes and his desire to learn, has made him a target at school.
