Using only dialogue as its narrative technique, Luis Zapata recounts the story of his protagonist Santiago, a middle-aged businessman hopelessly in love with Arturo, a 19-year-old teenager, who is the son of Sarita, his best friend. Through skillful and entertaining dialogues during their courtship, which continue once the conquest is achieved, the novel reflects the deep generational chasm between the characters. Santiago is the completely dedicated representative of that mythical first generation of gringos born in Mexico--but in a gay version--who cultivates values and pursues goals in life and who believes in the middle-class version of national progress through personal and individual commitment. Arturo, on the other hand, is the typical postmodern teenager: pragmatic, addicted to working out, hedonistic, vain to the point of being narcissistic, cynical to the point of being cruel, and materialistic to the point of accepting money as the only God.

Thus, in The Strongest Passion, Zapata shows us that if indeed there are "women who love too much," there are also "homosexuals who love too much."
