In late 1991 John Waters published his best-selling book, 'Jiving at the Crossroads', a quirky and idiosyncratic scrutiny of the underbelly of Irish life in what would emerge as the dying days of an era. Shortly afterwards, a whole new Ireland would begin to be born, as though under the assault of some existential climate change. This latest work, 'Crossing the Road', takes the form of an extended letter by Waters to his dead father, Tom, in which he explores some of the changes in his own life and the life of Ireland in the quarter-century since his father's death.
