Queen of Clubs: A dynasty held to ransom (The 'Destiny' series Book 3) by Roger Penfound

As the Carter dynasty continues to expand into the turbulent 1970’s under the stewardship of Emma Malikov, the seeds of its impending destruction are inadvertently sown. Emma’s stepson, Michael, who has been groomed to take over the mantle of leadership, is seduced by the egalitarian views of the hard left and is steered by his radicalised girlfriend in a direction which sets him on a collision course with the family.
Emma’s reputation is riding high as her Cassandra chain of nightclubs become the entertainment venue of choice for the rich, powerful and famous. Her success seems assured when an American investor offers to help her establish the Cassandra brand in Las Vegas but she finds herself drawn into a murky world of corruption and intrigue as she attempts to negotiate a deal. Only the release of her former lover from gaol provides the emotional and physical support she needs as she battles with one crisis after another.
When her stepson is kidnapped and held to ransom, the links between politics, business and crime become all too apparent. As Emma fights to save the company against a background of political unrest and social turmoil, the values and ethics of the family are laid bare exposing the fragile foundations of the Carter dynasty.
