Mabel Sinclair never planned to become a pirate.

All she wanted was to escape her dull life as a debutante and conquer the world of fashion. One fateful night at a ballroom ends when Mabel's foolish brother is kidnapped and transformed into a toad. To save him, Mabel makes a bargain with a mermaid and travels with her to an unexpected realm of magic. Once there, Mabel must choose between being imprisoned by cruel merfolk or joining pirates.

A sailor who dreams of returning to his quiet life as a tailor, Antonio's plans are knocked off course by a chance meeting with the dashing pirate Mabel Sinclair. Antonio bonds with Mabel over their love of fashion, only to become a target for Mabel's growing list of enemies.

Fighting for their lives and their future, Mabel and Antonio find they have only one ally to turn to: the treacherous mermaid who Mabel bargained with in the first place.

The Mermaid's Apprentice is part of The Pippington Tales series and the first book of The Pirate and the Mermaid's Tailor trilogy, an epic tale of pirates, mermaids, and adventures in high fashion.
