This is sci-fi at its best: a contemporary love story as well as an engrossing view of our world in the future.The kinetically gifted, trained in mind/machine gestalt, are the most valued citizens of the Nine Star League. Using mental powers alone, these few Prime Talents transport ships, cargo and people between Earth's Moon, Mars' Demos and Jupiter's Callisto.An orphaned young girl, simply called The Rowan, is discovered to have superior telepathic potential and is trained to become Prime Talent on Callisto. After years of self-sacrificing dedication to her position, The Rowan intercepts an urgent mental call from Jeff Raven, a young Prime Talent on distant Deneb. She convinces the other Primes to merge their powers with hers to help fight off an attack by invading aliens. Her growing relationship with Jeff gives her the courage to break her status-imposed isolation, and choose the more rewarding world of love and family. less

As willful as her mother, The Rowan, ever was, and possessing unimaginable powers, Damia defies her family's attempts to tame and train her--only to bond with Afra Lyon, a Talent who serves The Rowan, and who becomes the object of her affection.

Damia and Afra-Raven-Lyon had reared their children in a brilliant and unorthodox way. All their young had been 'paired' when six months old with the furry, one-eyed Mrdinis, the only other sentient beings 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... moreDamia and Afra-Raven-Lyon had reared their children in a brilliant and unorthodox way. All their young had been 'paired' when six months old with the furry, one-eyed Mrdinis, the only other sentient beings 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 deeps of Space, Mrdini 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 -- all uniquely talented in their various ways, who were to play their part, helped by their life-long Dini friends, in the conquering and investigation of the Alien threat of the Hivers. less

The survival technique of the Hivers was terrifying -- and brilliant. Their huge Sphere ships, controlled by the Many Mind of ten to sixteen queens, surged out into space. When an appropriate planet was found, the Hivers destroyed any and every variety of indigenous life, the queens propagated, and when the new world was full, more ships were sent out. the colonization was repeated until no planet, no species, least of all Man and Mrdini, was safe... moreThe survival technique of the Hivers was terrifying -- and brilliant.

The furry and courageous Mrdini had fought the Hivers for centuries, many dying bravely in an attempt to save their own worlds. Now Mrdini and Man combined to form the Alliance -- and Humankind had their own weapons to offer -- the power and might of the Talents who could not only communicate silently with each other, but could project cargoes, ships and themselves across the deeps of space. The four children of Damia -- Laria, Thian, Rojer and Zara -- were Primes amongst the Talents, and all their skills were desperately needed, for the Hivers' terrible Sphere ships were still thrusting through space, unfathomable, impenetrable, and carrying death in their labyrinthine depths. less

Much had been done to limit and destroy the powers of the terrible Hivers, who had torn through space, annihilating every living thing that stood in their way. But still the Alliance had to discover the whereabouts of every last Hiver world and stop the Queens from further colonization.
