In a distant, bleak future, the inhospitable wasteland of Old Terra is pocked with colossal, self-enclosed cities: the Metrodomes. These megastructures form the pillar of the Solar Federation's power on the planet; Tyran is the oldest and, perhaps, most rotten of them. Ambra Feenix is a twelve-year-old Psyion; a human mutant with the ability to see into minds. She has learned to hide her secret well from the cruel world around her. But it seemed as though it was only a matter of time before she found herself in the Arena: a legal bloodsport for the cold-blooded disposal of undesirables by combat. Her chance encounter with Tryllan, a reluctant Hunter in the Arena, may be Ambra's last chance of survival and escape.
