The Little Mermaid meets Pygmalion...

Maribel has learned to stay quiet. As an orphan relying on the generosity of family, and with six outspoken and energetic cousins, silencing her own voice is often the easiest way to keep the peace and ensure her own acceptance.

After helping her cousin rescue Prince Frederick from a shipwreck, Maribel finds herself as the unwitting accomplice in her cousin's plot to marry the human prince. The plan is simple: Maribel will distract Frederick's grumpy best friend, Professor Hadrian Higsley, so that the scheming mermaid can cozy up to the prince.
Between a friendly wager over slippers, her growing attraction to a certain translator, the appearance of a foreign fiancée, and an increasingly desperate cousin, Maribel finds it harder and harder to remain a silent observer. Will she finally find the courage to speak? Or will the little mermaid choose once again to give up her voice?
