Of all the Rowan's children, Damia was the most brilliant, the most difficult, the loneliest, and the one who had inherited the greatest Talent. It was obvious from childhood that she was going to be a Prime, with all the honours, burdens and strains of that elite class. Her one friend was Afra -- older, wiser, Talented in his own way, but 'belonging' almost exclusively to the Rowan and the workings of Callisto Station.
As Damia grew up, her Talent became almost too strong to control, and the solution was separation -- from her parents, from Callisto, from her beloved Afra. Sent to the distant planet of Deneb, to her strange and gifted grandmother, Damia began the training necessary to turn her into a Prime of extraordinary gifts -- a Prime who could contact the minds of approaching aliens through space, some of whom threatened to totally destroy the worlds of the Nine Star League.
