Sophie ends her engagement the day she catches her fiancé cheating, then promises her best friend she'll house her son Karl while he trains for a swim competition. Karl is fourteen years younger, relentless, and very aware of the effect he has on her. She knows the rules and breaks them anyway.
The affair stays secret until two discoveries land at once: the woman her fiancé was cheating with is her best friend, and her best friend now knows about Karl. Sophie has to choose between the friendship she built her life on and the man who actually chose her, with both relationships hanging on the same confession.
