Corta Helio, one of the five family-corporations that rule the moon, has fallen. Its riches are divided up among its many enemies, its survivors scattered. Eighteen months have passed. Only Lady Sun, dowager of Taiyang, suspects that the last appointed heir, Lucas Corta, is not dead -- and that he is still a major player in the game. After all, Lucas always was the schemer, and even in death he would go to any lengths to take back everything and build a new Corta Helio, more powerful than before. But Corta Helio needs allies; and to find them the fleeing son undertakes an audacious, impossible journey -- to Earth.
