Psion: Joan D. Vinge

Book I of Cat. Telhassium was the key to the stardrive; the stardrive was the key to the Federation; the Federation controlled the Galaxy. But telhassium was found only on Cinder. And there was a plot afoot to hijack that godforsaken planet. Only team of dedicated psions could prevent a truly cosmic disaster. That team would not be complete without Cat, and Cat wanted no part of it! A new breed of humanity will be pitted against the age-old vices of hatred, greed and lust for power, with one added extra - the enigmatic, telepathic Hydrans, the only race among the stars to challenge mankind, whose defeat has left them with one last chance of revenge - PSION.
