But when she discovers that her supposedly reliable Mr Right is a distinctly unreliable cheater, she's forced to consider the possibility that everything she knows about relationships is wrong. In an effort to reinvigorate both her love life and her lacklustre career at posh magazine Country House, she sets herself a mission to date as many unsuitable men as possible. Toyboys. Sugar daddies. Fauxmosexuals. Maybe the bad boys she's never dated can show her what she's been missing in life. But if Mr Right can turn out to be so wrong, maybe one of her Mr Wrongs will turn out to be just right ...
