Allegra Sheridan is a jeweler designer in Manhattan. Though far from rich and famous, the young gemologist has made a name for herself designing one-of-a-kind pieces for a small but elite clientele - one of whom has offered Allegra an extraordinary opportunity.

For Allegra has in her possession a treasure worth far more than anyone imagined - one that contains a dangerous mystery and a scandalous past of international conspiracy that could mean death to anyone who discovers it...
