In 1985, he published his second collection, Fierro curvo (órbita poética) (Curved Iron (poetic orbit)), and in 1988 his third book, Castillo de popa (Poop Deck), which reflects the state of mind of a wide sector of Peruvian youth at that time in the face of the difficult years of the civil war and the galloping economic deterioration of the country.
He has also published the poetry collections El libro de las auroras boreales (The Book of the Northern Lights, Amherst, MA, 1995), Señora de la noche (Lady of the Night, Mexico City, 1998), El Zorro y la Luna.
