Apart from being a writer, Uranza was also an associate professor of Literature and the Humanities at Far Eastern University. As a playwright, she wrote for the theater, radio, and television. Her plays were produced by Channel 4 (television), DZRH (radio), and the Far Eastern University.
She has written the novels, Bamboo in the Wind (1990), A Passing Season (2002), Feast of the Innocents (2003) and the Women of Tammuz (2004). It spans a hundred years of Philippine history and, in terms of chronology, A Passing Season is the first, followed by The Women of Tammuz, after which Bamboo in the Wind came Martial Law by the former Philippine president and despot, Ferdinand Edralin Marcos. The fourth part of the saga is the Feast of Innocents, set in the Philippines' post-People Power period. Uranza's novels keep the Filipinos' history alive.
A Passing Season is the saga of families during the time of the twin wars of 1896 and 1898, known in history as the Philippine Revolution and the Filipino-American War. It is the story of the Eduartes, the de Almogueiras, the Herreras, and their neighbor and occasional friends, the Ricaforts, trying to hold on to old and trusted rituals of daily life amidst the turbulence and upheaval in the last years of the nineteenth century in Manila. It is a novel about ordinary people - of Tibor and Aurora, Masin and his cousin Subas, of Torcuato, the servant boy who knows no other existence, but who, in the end, establishes a kinship with the epical heroes of the nation because his sacrifice has not been less noble.
Women of Tammuz continues the saga with the stories revolving around the Eduartes and the Herreras right before and during World War II.
Set in Manila in the last beleaguered months before the politico-military take-over in 1972, Bamboo in the Wind tells of the last desperate efforts of a people fighting to stave off disaster. Amid the escalating madness of a regime gone berserk, an odd assortment of people - a senator, a young nationalist, a dispossessed farmer, a radical activist, a convent school girl, a Jesuit scholastic, including the Eduartes, the Herreras, and their friends - make their way along the labyrinthine corridors of greed and power. Each is forced to examine his own commitment in the face of brutality and evil, as the book conjures up scene after scene of devastation: the massacre of the demonstrators, the demolition of Sapang Bato, the murder of the sugar plantation workers, the burning of the Laguardia ricefields. And, as a climax to the mounting violence, that final September day - the arrests, the torture, and finally the darkness that overtakes the land.
In the Feast of the Innocents, we see the conclusion of the story of the Eduarte and Herrera families, who struggle to stay connected by means of their memories and the good they believe in, because these are the best weapons against the more sophisticated forms of present-day evil. Their fortunes have blended with their country's history in a counterpoint with the national dreams: their great-grandfathers had fought in the Revolution and the Philippine–American War; their fathers had gone to Bataan to fight a hopeless defense of their homeland; and they themselves had waged a covert campaign against a dictatorship. Now it is nearing the end of the next century and the country seems to be facing a hopeful time. The Eduartes and Herreras of the present generation must exercise eternal vigilance as they, like all decent Filipino families, confront violence, falsehood, and greed. Tony Eduarte comes face to face with a misguided colonel; Raul Herrera stands his ground against an unscrupulous newspaperman; Cielo Munoz tries to retrieve a child prostitute from the streets of Manila as she seeks to find meaning in the poverty and hopelessness around her. Feast of the Innocents is a novel of contemporary dreams and realities.
Uranza was also the author of the 2005 anthology of short stories entitled Voices in a Minor Key, a volume of 22 short stories, and a book of plays entitled Masks and Mirrors.
