Jo Edwards never planned to live on a barge. She’s not even sure she likes boats. But when her husband trades her in for a younger model, she finds her options alarmingly limited. Dora Hamilton never planned to run out on her own wedding. But as The Big Day approaches, she accepts Jo’s offer of refuge aboard The Three Sisters. As Jo and Dora embark on reorganising their muddled lives, they realise they both need a practical way to keep themselves afloat. But, despite their certainty that they’ve sworn off men for good, they haven’t bargained for attractive Marcus, and charming Tom, to help them out.
