The Craziest Month of Max McGuire's Life - Max McGuire Duology, #2

Max McGuire claims to have lived the craziest month ever lived in the history of the world. He lives in a treehouse in Coconut Grove, Florida, and drives a 1960 amphibious car. It is 1984 and he has a comfortable life, supported by a mail-order business. The moment Max decides to find the million dollars in gold that his now-dead father supposedly had, the craziest month of Max's life begins. First, a corpse falls out of his closet.
And it gets wackier from there. His only three lovers come back into his life at the same time. And not only does his three lovers come back, it is as if his whole crazy past comes back to haunt him. This is the second volume of the Max McGuire Duology.
