Shortly before his wedding, the unnamed hero of this uncommon romance is visited by a man, claiming to be his future self, who ominously admonishes the protagonist that he must not marry the love of his life, Q. The author doubts this stranger, but in time becomes convinced of his authenticity and leaves his fiancée. 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, opera, and eliminate gluten from his diet. The only constants in this madcap quest for personal improvement are the author’s love for his New York City home and for his beloved Q. Q turns the classic story of transcendent love on its head, with an ending that will melt even the darkest heart.
