Jason and Liana are the children of Aeren, a fugitive from the planet Ovanan, a world of powerful, beautiful and ageless psionics. Both children possess extraordinary powers. Jason, only 17 years old, is a disruptor, capable of short circuiting the energy systems in machines as well as in living beings. Liana, 15 years old, is the most powerful form of psionic in the known universe: she is an Avatar, a being who can draw on the life force of all the Ovanan people and wield that force as a weapon. Avatars are the religious leaders and protectors of Ovanan, but only one Avatar can exist at a time, and as long as Liana lives, she is a threat to Ovanan which has sent its massive warship the Siovansin to assassinate her.
