Karen and Jack celebrate their wedding anniversary the way they always do, on Primrose Hill, with flowers and a take-away. But this year is different.
This is writer Nicholas McInerny's autobiographical look at modern relationships.
Jack and Karen are nothing out of the ordinary. They have been happily married for years and are convinced every problem can be worked through. Until Jack decides he really is gay.
Seeking stability at all costs for themselves and for the children, they navigate the bumpy journey of finding a lover for Jack by going for the 'closed loop' arrangement. It sounds just about possible - in theory. But getting consensus all round for their 3-way partnership is far from straightforward. And Karen doesn't want to share her husband. She wants everything to stay the same.
