In his fourth journey, Ivan is led to a city inhabited exclusively by machines. Expectations of a highly technological scenario are broken when the book collector meets an apparently abandoned ghost town. Without many ambitions in the place Ivan decides to leave, but changes his mind when one of the inhabitants utters a known name in the conversation, and a gang which seems to have unfinished business with Ivan. The same cyberpunk scenario; the same intrigues and doses of action; the chaotic, pessimistic atmosphere are the ingredients for Ivan's fourth tale, the final one of his first cycle, about an universe in which the distance between man and machine is further blurred.
