Plot summary
David Mingolla is an artillery specialist in the United States Army serving in a near-future Central American war (references are made to then-future "Afghanistan in '89" and a nuclear weapon that destroyed Tel Aviv). As his unit serves in "Free Occupied Guatemala", Mingolla goes on leave and meets a woman named Debora in a cantina. They gradually become lovers; however, as they get close to each other, Mingolla feels intense mental pain later identified as a psychic probing his mind.
Soon after this, Mingolla is recruited into the Psicorps, an elite group of psychics the United States has assembled to counter the Soviet Union's own. Debora, a veteran of the revolt that led to American intervention in the first place, is designated his target. On his way through Psicorps training to refine his mental abilities, Mingolla learns that this front of the ongoing Cold War, as well as the war itself, is a manipulation by two Panamanian families, the Madradonas and the Sotomayors, over three centuries to increase psychic potential in humanity as well as their own genetic diversity.
Mingolla and Debora meet and part several times before their meeting with the Madradonas and Sotomayors in Darién, Panama and become embroiled with the members of Mingolla's former squad in a firefight which culminates in the nuclear destruction of Panama City. David and Debora leave the city and their former friends and antagonists behind them, deciding that ultimately what matters is their love for one another, the only item that has not been blatantly manipulated.
