Barbara Kingsolver trained as biologist before she became a novelist and she has repeatedly shown her desire to anatomise society in her fiction. In her bestselling novel The Poisonwood Bible (1998), she examined the impact of missionaries in the Belgian Congo and in her more recent novel, Flight Behaviour (2012), she took on climate change. In her latest novel Unsheltered, she turns her attentions to the recently disenfranchised middle class in contemporary North America.
Willa Knox is a woman under siege. Having strived for years, she newly finds herself a member of the precariat. The magazine she edited and the college at which her husband, Iano, taught both fold at the same time. The couple move into a wreck of a house she has inherited in Vineland, New Jersey, which they hope might be the answer to their prayers before realising it is so damaged as to be almost unliveable in.
