内容简介：
Graeme McCaig is thirteen and going to spend Christmas with his uncle. Lord Raversham, head of the Raversham family and ensconced in his castle on Raversham Isle, is dying (so they say) and seemingly powerless to stop his grown-up children from vanishing. Could these disappearances have anything to do with the strangers with large sacks who are gathering at night, down on the beach? Who is their cloaked, silver-masked leader and what is his plan? Graeme starts to investigate and finds himself caught up in an adventure that will see him collide with the Raversham family in more ways than one. He will make new friends. He will hate Calamara Jones. He will fly. He will fall. He will meet royalty. He will meet cannibalistic child assassins. He will learn of the legend of the Pyn King. He will find a new world. But can he save ours? For ages 10 and up, including unashamed adults. Parental guidance advised for those at the younger end of the recommended age range.
