Endospore is a story containing both elements of both fantasy and post-apocalyptic science fiction, written by R.A. Wilson, who has made it available as a free digital audiobook.

Alan is a virgin, but that is not a big problem for him with Tracy and Gwinn desiring his attentions. He has larger concerns on his mind. He is swept into the hidden underground of Midgard, once the shining jewel of enlightenment and technology. The city is regressing back to an unenlightened and viscous age following the end of the world in the Cataclysm.

All that remains is a corrupt governor and self-proclaimed god who rules all with an iron fist, a religious cult planning to dismantle society, and a rebel army who fights against Governor Fredrick. As Alan is pulled into the fighting, he finds it hard to discern friend from foe while desperately trying to find his place in the remnants of society. But when he discovers the secrets behind the Cataclysm, it becomes a struggle to save humanity from itself.
