Hatshepsut's Collar

An ancient Egyptian artifact is driving Queen Victoria insane, and that's not top of Cara Devon's growing list of problems.
Viscount Nathaniel Lyons is a man of numerous secrets, but there is one in particular that threatens his fledgling relationship with Cara. Stunned by Nate's revelation, and before she can absorb the ramifications of his actions, he is arrested, charged with treason and imprisoned in the grim Tower of London. He stole something the mad queen wants, and only has days to deliver, before his date with the executioner.
Although sorely tempted, Cara can't let him die on Tower Green, not when their connection means she would share his fate. Only together can Cara and Nate figure out how to wrestle Hatshepsut's Collar from around the queen's neck, before she plunges Britain into a world war. The search for answers sends Cara to the opulent Winter Palace of St Petersburg and the frozen depths of Siberia, with every step shadowed by an enemy with his own dark plans.
