Superfly by Melissa Ceseña

Fly On!

Eco-pirate Sarah Sumner and her devoted deckhand Gunner rejoin the motley crew on the M/V MerSea in the Southern Ocean during Operation Leviathan. From his own playbook, the captain decides to use the strategy of patience, evading the Japanese whalers, and visit Queen Maud Land in Antarctica.

The crew discover an ancient civilization. Trying to escape a gruesome sight, Sarah and Gunner stumble upon a lab managed by mad scientist, Paul, where Sarah learns more about her transformation into a mermaid.

Back on the MerSea, as the vegan captain and crew go nuts, Sarah and Gunner grapple with their new world through history, mythology, and religion. Caught in the middle of a war between world navies and spaceships, they are determined to find answers. There's a new predator at sea. It's not just the whalers anymore. How will Sarah fight her new enemy with a tail?

Superfly is a paranormal romance and book three of The MerSea Series complete with adventure, sensuality, and a happily ever after.
