Sisters-in-Law. They're not your choice - just your problem.

Sisters-in-law Kate, Helen and Olivia all have one thing in common - they're hiding something. It's not easy being part of the high-achieving Fox family: the expectations and demands of their husbands and children; the jealousies and rivalries; and the endless Sunday lunches where somehow everything feels like a competition.

So when mysterious Sasha enters their lives, bloodied from the battlefield of a painful divorce, buried frustrations rush to the surface. Why is Kate's husband Jonny working so late at the office, and how will she cope at home alone? Can army-wife Helen trust Jago to come back to her next time, or is he drawn by temptations in a foreign field? And will Simon's explosive secret blow Olivia's marriage apart once and for all?

Three sisters-in-law. One devastating divorcee. Whose husband is about to play with fire?
