Earth was at bursting point, in spite of the birth restrictions of only one child to each couple. Extra children existed in a sub-cultured world or were rounded up into slavery. The only hope was the space platform -- the jumping-off point for the colonization of other worlds. But more Talents were needed to build & operate those platforms.
Rhyssa Owen was the one responsible, both for finding Talents & training them. & when she felt the first encroachment of a mind reaching out to her, she knew it was exceptional -- a fourteen-year-old boy with incredibly powerful kinetic ability. & in the seamy underworld of near-criminal children was another brilliant mind in danger from a ruthless group of child kidnappers.
Rhyssa knew she had to find the two children & train them for the survival of earth.
