Sixteen-year-old Jill has fought in dozens of fencing tournaments, but she has never held a sharpened blade. When she finds a corroded sword piece on a Caribbean beach, she is instantly intrigued and pockets it as her own personal treasure.

The broken tip holds secrets, though, and it transports Jill through time to the deck of a pirate ship. Stranded in the past and surrounded by strangers, she is forced to sign on as crew. But a pirate's life is bloody and brief, and as Jill learns about the dark magic that brought her there, she forms a desperate scheme to get home—one that risks everything in a duel to the death with a villainous pirate captain.

Time travel, swordplay, and romance combine in an original high-seas adventure from New York Times bestseller Carrie Vaughn.
