Primary Inversion first appeared in hard cover in 1994 and was one of the strongest first SF novels ever, a romantic adventure with a healthy dose of super science. Not an unexpected gem, if one considers the author: Catherine Asaro holds a Ph.D. from Harvard in Mathematical Chemistry, Masters in Physics, edited her own SF/Science magazine, Mindsparks and had a previous Ruby Dynasty story in Analog, April 1994. Primary Inversion introduces us to our universe in the 2200's, but from the point of view of the genetically advanced humans that we discover seeded through the galaxy when we Earthlings finally make the leap to space. The Allied Worlds (Earth) holds one corner of the power triangle, but the struggle Sauscony (Soz) Skolia lives is between the Skolian Imperialate and the Eubian Traders (evil incarnate). She is the ideal of a perfect soldier. Jaggernaut physical training, a bio-web of weapons embedded in her body and a psi connection to the Skolian web that controls instantaneous communication in the universe make her nearly indestructible, but the fact that she's an empath and a telepath make her vulnerable in a way we rarely see in a killing machine. Throw in drop-dead-gorgeous and lonely as hell (no possibility of a Rhon mate, a man who can link minds with her, in the entire universe) and you see the formula for a novel filled with nova bursts of energy. Although this novel is meant to stand alone, it is actually the first half of a book. What is part two? The Radiant Seas (Tor 1999).
