The Immortal, Volume 1. The Immortal, #1

When Mandy, her husband and college-age daughter move into the home next door, Jim takes notice. After the death of his problematical last wife, the immortal man is living alone in a nondescript middle-class neighborhood. But he's soon teased from his solitude by Mandy's flashing eyes and impish grin. Together they embark on an adventure to push her sexual limits. and along the way reignite his faded dreams and dusty desires for a better life.
At the same time, ostensibly retired to cover his unchanging age, Jim is working with a shadowy force to maintain the natural balance between humanity and the varied supernatural communities that share his world. They know him as Iakovos the Undying. An incident has occurred. One that threatens that shaky equilibrium.(Volume 1 is a compendium of the first forty-four chapters of Jim's saga.)
