A forlorn psychoanalyst; a cultural historian exploring the possibility of life after death; a middle-aged couple that schedules a rendezvous with a younger version of itself; a man who compensates for his phobia of death and dying with intense sadomasochistic practices; and a writer who futilely explores the sexual habits and customs of Mexico City comprise the body of "Heaven is Hard to Swallow," the latest masterpiece of the phenomenal Mexican publisher, journalist, and fiction writer, Gay.
