Operation Luna — Poul Anderson

Poul Anderson, recently the winner of the Nebula's Grandmaster Award for lifetime achievement, returns to the world of his acclaimed novel Operation Chaos with the tale of one family's mission to the moon. Ginny Greylock and Steven Matuchek are partners an Earth quite unlike our own. For starters, Ginny is a licensed witch and Steve is an engineer and werewolf. Steve moonlights by working on a spacecraft in the Arizona desert, a project which soon discovers that there is life on the moon. Neither Steve nor the US government has any inkling as to the nature of the moonsprites, and everyone is anxious to make contact. But when the time comes to test the spacecraft, a host of bugs, snafus, and angry spirits conspire to prevent the launch. It's 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.
