Ada or Ardor: A Family Chronicle is a novel by Vladimir Nabokov published in 1969.
Ada began to materialize in 1959, when Nabokov was flirting with two projects: "The Texture of Time" and "Letters from Terra. " In 1965, he began to see a link between the two ideas, finally composing a unified novel from February 1966 to October
1968. The published cumulation would become his longest work. Ada was initially given a mixed reception.
