'-An Irresponsible Age', Lavinia Greenlaw's extraordinary new novel, is set in London in 1990, with Thatcher still in power but the country unwilling to 'abandon an idea just because it proved to be a bad one'. In these hesitant times we follow the life of Juliet Clough and her three siblings, all of them interdependent in a not-quite enviable way, clinging together after the death of a brother and the retreat of their grieving parents. When Juliet, the focus of them all, is drawn into a complex love affair with the enigmatic Jacob, the others, too, find themselves falling in love, and then evading the consequences. None will admit what they are doing, or why.
