Two Christians, an atheist and a witch walk into a bar.... in Cuzco, Peru, where they encounter Theo Duncan, an aimless history grad, who is only dimly aware that he's starving: for purpose, love, community. When he and his new companions aren't battling gators in the Amazon or getting swallowed by landslides in the Andes, they debate the number of deities which animate our world - zero? one? a bunch? - thereby transforming each of their lives in unforeseen ways.
