Mary

Mary is the queen of Scotland and the jewel of the French court. Except when she’s a mouse. Yes, Mary is an Eðian (shape-shifter) in a kingdom where Verities rule. It’s a secret that could cost her a head - or a tail. Luckily, Mary has a confidant in her betrothed, Francis. But things at the gilded court take a treacherous turn after the king meets a suspicious end. Thrust onto the throne, Mary and Francis face a viper’s nest of conspiracies, traps, and treason. And if Mary’s secret is revealed, heads are bound to roll. 

Mary may have inherited the brilliant mind of her late mother, Mary Wollstonecraft, but she lives a drab life above her father’s bookstore, waiting for an extraordinary idea that’ll inspire a work worthy of her parentage—and impress her rakishly handsome (and super-secret) beau, Percy Shelley. Ada Lovelace knows a thing or two about superstar parents, what with her dad being Lord Byron, the most famous poet on Earth. But her passions lie far beyond the arts—in mechanical engineering, to be exact.

Don't call this mermaid "little"—call her "captain," unless you want to walk the plank. Mary is in love with the so-called prince of Charles Town, except he doesn't love her back. Which is inconvenient. Since she's a mermaid, being brokenhearted means she'll—poof!—turn into sea-foam. But instead, Mary finds herself pulled out of the sea and up onto a pirate ship. To survive, she joins them.
