Katelyn is a devoted and avid explorer of all things human despite the losses she had sustained from the destruction of her people by the human populace. But with her father and brother missing from home after an exploration, she takes it into her own hands to go the surface to find them. It's when she washes up on shore does she meet Keith, a surfer who lives with his brother on its shores. What she wanted was her family back, but what she didn't expect was to fall in love with a human. A Little Mermaid!AU that no one asked for.
