On a lark, journalist Danny Wallace placed an ad in a small London paper that offered two simple words: "join me." What followed was astounding. From all over the world, thousands of replies poured in, effectively "joining" Danny-but in what, he had no idea. When "Joinees" began referring to him as "The Leader," Danny quickly understood one thing-he had just created a cult. Join Me quickly became a phenomenon. With the help of a few trusted Joinees and the crackpot leader of a well-established cult, Danny promulgates his uncle's dreams of a Utopian society, struggles to keep his girlfriend, manages to stay humble amidst the newfound celebrity, and remarkably provides a sense of purpose and belonging to Joinees everywhere.
