Having escaped certain disaster on the high seas, Atticus Van Tasticus is on the scent of treasure. Then the call comes from above- ‘Ship ahoy, Captain, ship ahoy!’ If only it were good news, which of course it ain’t. Vicious, mean and mighty unclean Bjorn Ironhead is on the warpath – and Atticus and his crew are in his sights. Stay and fight, or run and hide? But where do you hide a pirate ship, and who’s this Captain Half Map, and, most of all, where’s that TREASURE OF TREASURRRRES?!
