Miss Heather (Calluna Vulgaris) Morgan is set to embark on her most harrowing assignment with Bow Street. After an incident sees her engaged to an earl suspected of dastardly doings, she and her fellow runners devise a plan. She must set sail with her new, monstrous fiancé, bound for the Americas...all while attempting to uncover proof of his treachery.

But she won't be alone: her dashing and mysterious combat instructor has valiantly offered his aid.

Percy Baxter vowed he would never return to life at sea, for he was no longer that man. But when one of his students from Bow Street takes on a daunting assignment on board a frigate full of untrustworthy men, he knows he simply cannot let her go alone.

Shortly into their voyage, however, they're set-upon by a ship of pirates notorious for leaving no one alive. Together, Heather and Percy must weather battles, storms, and secrets, all while the passion between them threatens to engulf them both.
