Things quickly go from bad to worse as Emily, Captain Fly Austen, and young Magpie each find themselves in treacherous waters. In late September 1813, Fly Austen, now a captain, is ordered back to the American coast as England’s Royal Navy has suffered a series of humiliating defeats. Forced to return to sea with a skeleton crew, Fly persuades a reluctant Leander Braden to accompany him one last time. Emily, realizing the plan is to leave her in Portsmouth with Leander’s aunt, disguises herself as a man and steals aboard Fly’s frigate, where she is tormented by his passengers. Meanwhile, young Magpie is captured by a press gang and hustled aboard a hostile ship, only to find himself in the dangerous company of Thomas Trevelyan, the English traitor who escaped incarceration on a prison hulk. A shipwreck, a mutiny, and a bloody encounter with American ships on the Atlantic inflict devastating consequences on all.
