Juliana, the "anti-heroine" of this story, was first introduced in an eyewateringly sad moment in the prologue to "The Earl's prize" which is set on the day that her mother left home, deserting her husband and two children. (Juliana's elder brother is Joss Tallent, the hero of "The Earl's prize.") As the carriage left the grounds her mother looked back and saw something moving in the nursery window: five-year-old Lady Juliana Tallent was waving goodbye.
By the start of the main action of both that book and this one, Juliana has become Lady Juliana Myfleet, an outrageous widow whose gambling and flirting provides all manner of scandalous gossip for "the ton," as high society was known.
But then she meets the one man who, despite his prudish disapproval of her antics, makes her wish she was more respectable ...
Silly but entertaining. It's not Jane Austen - what is? - but reading this is an amusing way to spend an hour if you like light regency romances
