One rule.

That was all his wife asked.

Cal and Corinne's marriage has been quietly unraveling for years, so when she proposes an open marriage, it comes with a single condition.

No feelings.

One night.

No repeat partners.

No exceptions.

It sounds simple enough.

Then Cal meets Sabrina.

What begins as one honest evening with a woman who has no interest in becoming anyone's secret slowly becomes the one place he feels truly alive. Late-night conversations over fresh bread, music he hasn't played in years, and a connection neither of them planned begin breaking the only promise that mattered.

Because attraction was never the danger.

Falling in love was.

Now Cal must decide whether protecting a marriage that quietly ended years ago is worth losing the woman who helped him become himself again.

Sometimes the hardest rule to keep... is the one that was never meant to save you.

My Wife's One Rule is an emotional contemporary romance filled with forbidden attraction, quiet longing, explicit heat, and a deeply satisfying happily ever after.
