Danger is on the horizon!
Join Patrick and Beth in a seafaring adventure set in 1781. The cousins accidentally land on an American ship and are befriended by 15-year-old freedom-fighter James Forten. After a battle at sea, the ship is captured and the sailors fall into the hands of their British enemies. Things then go from bad to worse. Beth gets in trouble with the cook. Patrick is caught up in a sword fight. And James might be sold to a ruthless slave trader. Can a handful of marbles and an ordinary onion save them all from certain disaster?
