Description: Damia and Afra Raven-Lyon had reared their children in a brilliant and unorthodox way - 'pairing' them when six months old with the furry, one-eyed Mrdinis, the only other sentient being in the Alliance, who could communicate with humans by their 'dream messages.' Together, Man and Mrdini worked to create prosperous worlds and guard against the terrible threat of the annihilating Hivers. And now, in the depths of Space, Mrdinin scouts had crossed the path of three Hive ships - ships that were giant hulks of cell units, bearing the queens and workers out into space, to breed and multiply and destroy wherever they found a viable planet. It was the four elder children of Damia - Laria, Thian, Rojer and Zara, with their 'Dini friends who had to use their talents to prevail against the Hive.
