Anderson Poul Operation Chaos

The prequel to the popular Operation Luna.

In a war waged against black magic, a werewolf and his witch wife are called upon to neutralize an enemy's ultimate weapon--the world's most powerful demon.

Set in a fantasy alternate history United States where magic and technology combine. Werewolfery is not only hereditary, but a recessive gene, and the polarized component of moonlight has been isolated, so that the hero can use a Were-flash to transform without the full moon.
