Public buildings and monuments are collapsing around the world... and no one knows why! A reclusive multinational corporation claims to have found the answer. Finnley McDougall and his best friend Hadley are growing apart from each other as things at school become weirder and weirder. Tessa of the Golden Star remains stuck in the wrong place and time. Wullie-The-Mahaar-Gome, their scruffy, rude, bad-tempered protector seems unable to help. Despite the victory in the Battle of Tårsjo Plain life on the planet does not seem safer. Power in the gome world is shifting to a city in Central America ruled by a cruel tyrant who uses slaves to build up his empire and protects his city by a volcano below and a lake up above filled with murderous bull sharks. Can anything restore balance between the worlds of gomes and humans? The answer may lie in an inaccessible canyon on the Navajo Reservation on the Colorado Plateau that is drawing in the attention of the world.
