By the mid-twenty-first century, humanity is beginning to enjoy membership in the Galactic Milieu, a confederation of exotic races spread throughout the galaxy. Human colonies are thriving on numerous planets, life on Earth is peaceful and prosperous, more and more humans are being born with the metapsychic abilities that characterize the next step in human evolution . . . and it is not long before these gifted minds will at last achieve total Unity. But xenophobia is deeply rooted in the human soul. And ethnocentrism all too often rears its ugly head. A growing corps of rebels plots to keep the people of Earth forever separate in the name of human individuality. At their head is a man obsessed with human superiority: Marc Remillard, scion of the family that almost singlehandedly led humanity into the Galactic Milieu, and one of the most formidable metapsychics ever. Marcs goal is nothing less than the elevation of human metapsychics above all others, by way of artificial enhancement of mental faculties. His methods are unpalatable, his goal – a great generation of bodiless brains with gargantuan metapsychic powers – is horific. And so Marc and his co-conspirators are forced to continue their work in secret, not only to implement the Mental Man scheme but also to eventually take over the Milieu by force. Only the very Unity he fears and abhors can foil Marcs plans. And only his brother, Jack the Bodiless, and the young woman called Diamond Mask – and the awesome power of their combined minds – can hope to lead the metaconcert to destroy Marc, Unify humanity, and pave the way for the Golden Age of the Galactic Milieu to begin . . .

The eagerly awaited finale of a modern SF classic–Mays Galactic Milieu Trilogy, which began with Jack the Bodiless and continued with Diamond Mask. The mystery involving Jack the Bodiless, the metaphysically talented Dorothea, and Fury, the insane metaphysic creature determined to become sole ruler over all humankind, explodes anew. At last, the momentous secret at the heart of the trilogy is revealed.
