The Longevity Thesis is at turns darkly primeval and disconcertingly modern, grimly macabre and life-afirming: compounded together, these ingredients create a powerful and unsettling tale. The Temlochti State University is the centre of scholarship in an underground land, where the inhabitants have so long avoided the desert above them that many now regard the stories of its magic as mere superstition. Antronos, who has been touched by that magic, knows better. But even he does not suspect what ancient and unnatural beings are at work within the University itself, until his desire to study longevity places him in their power. Jennifer Rahn is a daring new voice in dark fantasy, and I hope that she will give readers a chance to explore this world further.

Deformed by the desert he had been born in, Antronos had fought hard to overcome the stigma of being a surface dweller and make his place in the underground civilization of the Temlochti State. Finally accepted in academia, he graduates with a degree in medicine and accepts a position as a graduate student in the laboratory of Sen Vernus, a Professor Emeritus who demonstrates an extensive and arcane knowledge of longevity.

The weak-willed Lord Jait possesses psychic power he has no idea how to use-power that Vernus can use to possess others. The 'longevity' studies progress from stealing body parts to control over entire beings. Can Antronos resist the mind invasions of Vernus or will he destroy Lord Jait, the very man he has vowed to save?
