It is a continuation of
To Ride Pegasus. We are 50+ years on after the discovery of Talent as a science and helpmeet to the rest of the world. There are more centers all over the world, the Western US, Australia, Hong Kong, Southern Asia, etc. Society is more accepting of Talent as a whole.
While Rhyssa Owen (Director of Eastern Parapsychic Center and granddaughter to Daffyd op Owen who ran the center immediately after Henry Darrow and helped to pass protective legislation benefitting Talent) was asleep one night when a mind touched hers and jolted her out of a sound sleep. Normally a Talent's living quarters are shielded so they are not inundated with psychic noise the rest of us can't hear. It would take quite a bit of mental strength to achieve such a feat and Rhyssa is intrigued by the person who was able to do it. During the course of the story, she discovers Peter Reidinger.
He was paralyzed by a wall collapse and is confined to a bed. At night and unable to sleep, he "travels" to a serene place in his mind where trees and gardens grow. He thinks it's someplace he's been before. During these nighttime wanderings, he touches Rhyssa's mind. She discovers the strength of his Talent and encourages his family to entrust his care to the Eastern Parapsychic Center where she can personally direct his care and training.
As with all mentors, she is nervous that he will burn himself out and be unable to use his skills so she handles him with "kid gloves." As with all kids, he's impatient for more. He is able to use his kinetic skills to "move" his paralyzed body. But he goes beyond all expectations for he is able to tap into electrical sources to augment his power.
This is the jumping off point for the Tower & Hive series. Without Reidinger's discovery and ability to communicate telepathically and utilize telekinesis, there is no Rowan or anyone living amongst the stars.
