Cruise Ship Rules

Every milestone anniversary, Mark and Julia Holloway take the same cruise, live by the same rule, and come home more in love than they left: whatever happens at sea stays between them, as long as neither one keeps a secret past the dock.

Twenty-two years married. Ten years of this exact tradition. Zero regrets.

This year, the tradition gets company.

Chloe is twenty-one, gorgeous, and has never once heard a man tell her no — and she’s decided Mark is going to be her biggest trophy yet, marriage be damned.

Her quieter best friend Sienna just wants to survive the week without getting dragged into the scheme — until Julia notices her first, and shows her exactly what she’s been talking herself out of wanting.

What Chloe doesn’t know is that Mark and Julia clocked her the moment she opened her mouth at the sail-away bar — and they’ve been running the whole game from the other side since day one.

Every flash, every dare, every whispered plan gets reported straight back to their bed.

By the time Chloe springs her trap on gala night, she’s about to find out exactly whose hunt this always was.
