Lunatics — Bradley Denton

Jack has been widowed for close to a year, and his behavior has his friends worried. Arrested for public indecency, Jack insists that he was meeting a moon goddess of desire named Lily. Furthermore, he claims that she can only find him if he waits outside, naked under a full moon. To prevent further troubles with the law, Jack's friends begin taking him to a cabin in the woods each full moon. But one at a time, they are each touched by Lily and forced to deal with their desires before they can truly know their hearts.
