When Isabella Wyndham-Brown returns to London to celebrate her 21 birthday, she anticipates nothing more than a ball in her honor and the right finally to direct her own life away from the restraints of her well-meaning but interfering relatives. But events almost immediately conspire against her. First she discovers that she cannot take control of her fortune until she is 25 and then she finds disturbing evidence that her father had a mistress. Nevertheless, there are compensations, including meeting her handsome French cousin and Peter Bennett, who saved her life in Egypt. But it is when she discovers that her father may have found the lost family treasure, the Dragonsheart diamond, Bella's problems really begin.
