Mermaid Spell

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

On a hot summer day, and on a popular beach; while soaking in the beauty of nature, Colin encounters an entity different from his kind. He is cast under a spell by a mermaid and sucked beneath the beach water where he is taken to an unknown world. He is assigned on a mission against his human kind, and given certain rules to follow in exchange for his heart desire.
With time, he gets too comfortable and breaks a golden rule requiring him to never fall in love with a woman. The consequences are dire, and there is no forgiveness in their book.
Colin flees for his life, and protects the outcome of his disobedience; his unborn baby. Can he elude them, or will they catch up with him and end his life?
