This book starts brilliantly; Ben has just walked out on Rose after some 20 years of marriage, with no discussion, no explanation. The novel then switches between Rose's attempts to cope, and the early days of their relationship back in the 70s. The format works well, as in the present day Rose discovers just how far she's been betrayed.
Many people will be able to identify with this story, especially women. And Dunne places it in a national context too, such as views on divorce in Ireland.
But about half way through, the format falls apart and no longer works. We have bits and pieces from Ben's perspective - and even more unconvincingly from the mystery woman as well - and the story generally meanders and slows down.
At first the simplicity of the writing is its strength, but then it becomes rushed and clichéd ridden
