Near the Land of the Dead:
Iset is juggling a gang of tomb robbers, a younger brother, a sick mother, and a multitude of secrets that could ruin the lives of her close-knit family. Just as she learns her life is in danger, she runs straight into the most unusual man she's ever seen. Can she trust him to help her, or will he hasten her demise?

Batr, one of the queen's Royal Guard, is determined to find the men behind the desecration of a nobleman's tomb. But when he's drawn into a web of mystery, he finds Iset at the centre of it all. And she's the most intriguing woman he's ever met.

Meanwhile, in the court of Abdju:
When Raia learns her father's tomb has been robbed, she resolves to see the perpetrators punished. Aided by Makae, Batr's twin brother, they uncover a series of confidences that force Raia to question everything she's ever known.

Follow the two couples through the painted tombs of the Land of the Dead and into the treacherous world of ancient nobility as they seek a gang of dangerous thieves who threaten the peace of both the living and the dead.
