The last thing Mabel needed was a flying saucer, not to mention a rash of similar sightings all over town. Her life's already been upended by getting fired and moving to Grandma's old house in Medicine Spring. So far, the deceptively sleepy village has delivered several murders-and romance with a handsome private investigator. Are little green men next?

While Mabel tries to get to the bottom of the apparent space invasion, she also gets herself caught between competing candidates for township supervisor. Small-town politics call for more diplomacy than she has-not to mention the ability to duck, run, and hide.

And unfortunately, her UFO investigation only raises more questions. Long-buried secrets surface, all tied to one night in 1958 and another seeming alien attack. But something more troublesome than any Martian invasion is on its way. A film crew descends, bent on producing a documentary on the historic UFO crash. Hordes of tourists follow, all infected with flying saucer fever. When an all-too-human body turns up at the alleged alien gravesite in a local cemetery, Mabel realizes murder is bound to follow her, whether of this world or not.
