Beneath the Gated Sky

From the dust jacket flap of the Tor first edition: "Beneath the Gated Sky picks up where Beyond the Veil of Stars left off, leading us through worlds of wonderment and betrayal in a universe of unlimited possibilities. The stars no longer shine at night. The Portal fills the sky, reflecting the earth's image back at itself. The Cosmic Events Agency sent Cornell through the Portal, to an alien world where he and a beautiful woman named Porsche together infiltrated the planet's native population for the sake of humanity. But Porsche is not human. She is one of the Few: a race of shape-changing aliens that secretly lives on millions of worlds across the universe. Unfortunately, Latrobe, leader of the CEA, also knows of the Few. And he has a diabolical plan of his own."
