Filtered through the recollections of the author’s grandmother Gabriela Paez Viardo de Velasquez, The Three-Cornered Sun follows the lives of the members of the Viardo family as they go through the turbulent times of that tumultuous year—sometimes on opposing sides. First published in 1979, the historical novel is interspersed with appearances of notable figures of the period, such as Andrés Bonifacio and Emilio Aguinaldo.

In a new foreword written for this edition, historian Manuel L. Quezon III notes that The Three-Cornered Sun “is more accurately a story that explores how the revolution was itself a confrontation between Filipinos.”
