I wanted to put presence into absence. I was very frustrated that black British women weren't visible in literature. I whittled it down to 12 characters – I wanted them to span from a teenager to someone in their 90s, and see their trajectory from birth, though not linear. There are many ways in which otherness can be interpreted in the novel – the women are othered in so many ways and sometimes by each other. I wanted it to be identified as a novel about women as well.
