The British crown has placed a price on Jacky's head, and so she returns to the Lawson Peabody School for Young Girls in Boston to lay low. But laying low isn't in the cards for a spunky lass who finds trouble even when she's not looking for it.    A school outing goes awry as Jacky and her classmates are abducted and forced into the hold of the Bloodhound, a ship bound for the slave markets on the Barbary Coast. All of Jacky's ingenuity, determination, and plain old good luck will be put to the test as she rallies her classmates to fight together to avoid being sold on the auction block in this new installment of the Bloody Jack Adventures.
