The Avalon Job - Hollow Moon, #4

Ravana O'Brien is confronted by her past in more ways than one. Secret agent Kedesh is back on the scene, seeking help for a mission to Alpha Centauri. Artorius, the young boy taken by Que Qiao agents after fleeing the Dhusarian Church, has been traced to a shadowy American base on the moon of Avalon. A second alien portal has been found, a mysterious ancient machine that can twist space and time.
Avalon is no ordinary world. The moon hosts epic holovid events, not least the vicious celebrity show Gods of Avalon, a game based on the legends of King Arthur where players fight to survive against cyberclone beasts. Infiltrating the secret base means getting past the game arenas, but Ravana cannot trust the slippery Kedesh and has enemies old and new out to see her fail. The rejuvenated Priest Taranis, now with the might of the new Terran Federation of Worlds at his disposal, is pulling the strings. He has a new chosen one, a man called The Raven who seeks Ravana's doom. A rumour of hidden gold is sowing confusion. Artorius is the key to those who want the alien portal open. Watchers are playing the ultimate game.
