|| Shortly before his wedding, the unnamed hero of this uncommon romance is visited by a man who claims to be his future self and ominously admonishes him that he must not marry the love of his life, Q. At first the protagonist doubts this stranger, but in time he becomes convinced of the authenticity of the warning and leaves his fiance. The resulting void in his life is impossible to fill. One after the other, future selves arrive urging him to marry someone else, divorce, attend law school, leave law school, travel, join a running club, stop running, study the guitar, the cello, Proust, Buddhism, and opera, and eliminate gluten from his diet. The only constants in this madcap quest for personal improvement are his love for his New York City home and for the irresistible Q.
