Siobhan Greenfield is a pirate captain, treasure hunter, trouble maker and, as it would seem, also without a ship. For years she has been searching for a legendary treasure that could seal her future within the Seven Isles. But the sudden reappearance of an old acquaintance has set her entire crew against her, and Siobhan's plans have been thrown into disarray.
Siobhan is determined to beat her former crew to the treasure, but she can't do it alone. She'll need to procure the aid of a bitter navy commander, a runaway noblewoman, and a hapless young cabin boy who appears to know more than he is letting on.
Time is short, and the odds are against them. What lengths will Siobhan go to ensure her name becomes legend?
