Josh Emmons

June 30, 2008

If the title of Josh Emmons's sophomore novel, "Prescription for a Superior Existence," sounds more like a Dr. Phil-type self-help book than a work of fiction, that's entirely purposeful. Emmons takes on trendy religious sects like Scientology and Kabbalah in the story of a 30-something man disgusted with his life who turns to a group called the Prescription for a Superior Existence to find a more fulfilling life, or at least a more fulfilling lifestyle, and winds up getting forced into the group's training camp against his will. Emmons reads from the book tonight at Porter Square Books. 7 p.m. Free. Porter Square Books, 25 White St., Cambridge. 617-491-2220. portersquarebooks.com
