Growing up in New England, Danielle Larson spent her entire life loving the water. The Chesapeake Bay was a home away from home for the Maryland native, and a place that she felt safe and comfortable in, until the day of the accident. In an attempt to get her terminally ill husband to shore after running out of gas in the middle of the bay, Danielle found herself in quite a predicament when the blade of her boat nearly took off her leg. The heroine survived the accident, but weeks later something strange happened. As gangrene and fever began to consume Danielle's body, a mermaid in the bay happened upon a sandal she had lost the day of the mishap and Danielle found herself face to face with a mermaid named Zennor. Zennor offered Danielle her own body and a chance to look after her family as her body deteriorated in the hospital. Danielle, a woman born to protect her loved ones, jumped at the opportunity to keep her family safe. What she didn't know at the time was what she had agreed to give Zennor.
