Jeff and Kitty Katt-Martini and the rest of the American Centaurion Diplomatic Corps are still recovering from their introduction to Washington D.C. politics, parties, and conspiracies. New worries in the form of evil androids running amok, birds of all kinds and from all places creating havoc, a Senator trapped in an ever-tightening web of intrigue, and escalating international tensions all seem tough but manageable.

But the disappearance of Jeff Martini and Charles Reynolds during the International One World Festival signals more than the usual nastiness—and it looks like even ACE can’t help them. Then more trouble arrives, and even with the best hackers in the world, the full might of Earth’s military, and the Wonder Twins on their side, Centaurion Division’s outmanned . Now Kitty’s racing against the clock to find not only Jeff and Chuckie, but to keep the peace between Middle Eastern countries, all while searching for the bases of super-soldier operations—to stop them or die trying.

Alien vs. Alien is the thrilling sixth installment of the Alien novels.
