Here's a synopsis of the book:
Antronos knew nothing but the Desert. Full of sandstorms, hallucinogenic dust dreams and the strange undead, he would have gone insane if not for the magic of his mother that held the demons at bay. One day, his mother died.
The underground civilization of the Temlochti State did not readily accept Antronos the surface creature from the Desert. Enduring constant derision, Antronos sometimes managed to find work along the docks of the underground river that made life rich and easy for the tunnel dwellers. After saving a university professor from drowning, he was granted a studentship in medicine.
Thinking that understanding life and death might help him one day at least accept, if not understand, the strange way in which his mother had died, he decided to pursue a graduate degree after he became a medical doctor. His research topic: longevity.
Unfortunately, his graduate supervisor's methodology is less than ethical, and he hates Antronos with a passion. Antronos is tricked into committing an act of murder. He is then blackmailed into doing Sen Vernus' dirty work as the old man grabs power: political power, psychic power, magical power, with the aim of taking over the minds and bodies of the most powerful and rich people in the state.
He may die, but Antronos has decided to rebel.
