The body of a mermaid is a vault of treasures. Their tears formed the most splendid of pearls, their exquisite blood a euphoric drug for vampires, their luscious hair woven into the finest of silk, and their tender meat sought after by werewolves more than Heaven’s ambrosia.

Genevieve Barlow, Eve for short, was an exceptionally strange young lady. She had an alluring and beguiling nature, where for her twenty-four year old self had barely changed in appearance since her eighteenth birthday.
