Writer and broadcaster Gyles Brandreth has chosen EF Benson's entertaining tale of competitive snobbery in the 1920s, Mapp and Lucia. In a contrasting choice, neuroscientist Hannah Critchlow advocates for Transcendent Kingdom by Yaa Gyasi, a story of a Ghanaian family transplanted to Alabama which takes in neuroscience and opiate addiction. Harriett has gone for a real crowd-pleaser in E. Nesbit's The Railway Children and all three enjoy a bit of nostalgia for the times when children could run free having adventures around the railway.
