So when Ainsley realizes her marriage is at its breaking point, she makes a decision to repair it, no matter the cost. Approaching her husband to propose the arrangement is supposed to be the hard part, but Peter agrees to the salacious plan almost immediately.

The rules are simple:

They will each date someone new once a week. 

They will never discuss what happens on the dates. 

Soon, though, the rules are broken, turning terrible mistakes into unspeakable consequences. 

When the only person they can count on to keep their darkest secret is each other, new questions and deceits surface. Can they truly trust the person they share a life with, or will the vicious lies that have mounted over the years destroy everything they’ve built?

Once, Peter and Ainsley vowed to stand together forever, but as they push boundaries of deception, suspicion, and temptation, each begins to wonder if ’til death do us part may come sooner than they’d intended.
