Now, Sue McEwen-daughter of ace detective Gil McEwen and fiancée of Steve Thatcher, the Moon Man-is their latest target. Gil and Steve save Sue before she can commit any crimes, but the drug's effects linger. Torn between the Nine Spheres' dark influence and the Moon Man's hidden identity, she spirals into madness under the moon's eerie glow. Can Steve break the Nine Spheres' deadly grip before it's too late?
