Flynn is no longer welcome at the Baskervile orphanage — so he signs up as cabin boy aboard the pirate ship Black Hound. But nothing could prepare him for what comes next.
A priceless golden chalice has been stolen from Fergus McSwaggers, the fearsome leader of the Bog Islands, and he’ll stop at nothing to get it back. Now Flynn and the crew must take on their most dangerous mission yet — facing off against ice pirates, feuding clans, and the most terrifying creature on the Seven Seas: the monstrous Mogdrod. Can Flynn survive his second adventure… or will this be his last? (Book 2)
