Susie and Alex have been together for ten years. Most of them happy. They have two beautiful kids, successful careers and a lovely house in London. But an overheard conversation leads to a misunderstanding, and the misunderstanding leads to consequences larger than anyone involved could have imagined...

Narrated in turns by Susie, Alex and his mistress, Pippa, Separate Lives is a searingly honest and at times brutally funny novel about modern marriage.
