Strange Invasion

A man prone to horrifying hallucinations is contacted by an alien race benevolently bent on preventing a series of invasions of earth by a variety of "tourists". But this...is not a horrifying hallucination. This is the real thing - and for Wally Griffith, longtime psychiatric case, it's the Campbellian call to take up the hero's journey. He enlists the aid of others en route to each adventure.
