The Royal Alexandrian Library faces threats in the twenty first century, from both the Soulless Brethren who want to make a fortune from the Libraries secrets using the power of two mystical objects they've discovered and Omar Gamel a billionaire who simply wants it for himself.
Amanishakete and Sabine must brave the perils of travelling back in time to 6th century BC Lydia in Asia Minor to change history and then to the Hoggar Mountains in the Sahara for an audience with Tin Hanan, the 4th century AD Queen of the Tuareg.
With new Adamantine weapons, made from an ancient mythological formula found in the Royal Library, Amanishakete and Sabine must confront the challenge of an inheritance from the now deceased Gamel and an attack from the Soulless Brethren.
