The Winter Serpent

This is an Apple Books audiobook narrated by a digital voice based on a human narrator.

Ruben Holland has spent the last five years as a wandering adventurer. He returns home to less than a hero's welcome.  However, when crops begin to fail and a mysterious cult of snake worshippers arrive, Ruben is enlisted to help find the cause of the trouble. Together with an assassin, a priest, an elf, a Northman warrior, and a hunter, Ruben must solve a mystery that may have dire consequences for the whole world. Will Ruben be successful and become the hero he thinks he is destined to be, or will the world be sucked into an eternal winter?
