Entitled mermaid princess rescued by skeptic hot geek marine biologist. Ilsa has looks, mermaid magic, and charm, but responsibility? Not her thing. It is her duty to protect river life, but she avoids this obligation by extending her holiday in the New World. Duty finds Ilsa when she answers a distress call in the waters near Chattanooga. A close encounter with a motorboat threatens to expose the existence of mermaids until human biologist Paul Pulaski comes to her rescue and covers her tail. Paul is committed to protecting the aquatic life he loves. He could love Princess Ilsa, too, but first they’ll have to survive monster hunters, rival scientists, and an angry river guardian who could destroy their colliding worlds.
