Poul Anderson returns to the world of his acclaimed novel Operation Chaos with a tale of one family's mission to the moon.
Ginny Greylock and Steven Matuchek are partners on an Earth quite unlike our own. For starters, Ginny is a licensed witch and Steve is a werewolf. Steve moonlights as an engineer working on a spacecraft in the Arizona desert, along with Will Greylock, Ginny's older brother. Will has determined that there are intelligent beings on the moon. Neither Will nor the U.S. government has any inkling as to the nature of these moonsprites, and everyone is anxious to make contact. But when the time comes to test the would-be spacecraft, a host of bugs, snafus, and angry spirits conspire to prevent the launch.
It is a recipe for perfect lunacy as Ginny and her clan struggle to figure out who, or what, is sabotaging the greatest magical and scientific achievement of the century.
