A prophecy warns of danger threatening the peaceful colony of Rockhopper penguins on the Falkland Islands. As Hopper's family tries to figure out what the danger is and how they should prepare to meet it, his son, Jumpin' Jack, travels into the Pacific Ocean to seek adventure. Before long, those remaining at home become convinced that Jack is heading into the foretold danger, that he is about to fall into a trap set by the evil Great White Seal. Can they find a way to rescue Jack before it's too late? This is the second book of the Fly Like a Penguin trilogy, continuing the story which began in Volume 1, The Long Way Home.
