Lucette. The story begins when Van, aged 14, spends a summer with his cousins, then 12 and 8. A rough idea of the years covered by each section is provided in brackets, below, however the narrator's thoughts often stray outside of the periods noted. Part 1: 43 chapters (1863–1888) This part, which one critic called "the last 19th-century Russian novel", takes up nearly half the book. Throughout this part of the novel, the many passages depicting the blossoming of Van and Ada's love vary in rhythm, style and vocabulary—ranging from lustrous, deceptively simple yet richly sensual prose to leering and Baroque satire of eighteenth-century pornography—depending on the mood Nabokov wishes to convey. The first four chapters provide a sort of unofficial prologue, in that they move swiftly back and forth through the chronology of the narrative, but mostly deal with events between 1863 and 1884, when the main thrust of the story commences. They depict Van and Ada discovering their true relationship, Demon and Marina's tempestuous affair, Marina's sister Aqua's descent into madness and obsession with Terra and water, and Van's "first love", a girl he sees in an antique shop but never speaks to. Chapters 4 to 43 mostly deal with Van's adolescence, and his first meetings with his "cousin" Ada—focused on the two summers when he joins her (and her "sister" Lucette) at Ardis Hall, their ancestral home, in 1884 and 1888. In 1884 Van and Ada, age 14 and 12, fall passionately in love, and their affair is marked by a powerful sense of romantic eroticism. The book opens with their discovery that they are in fact not cousins but brother and sister. The passage is notoriously difficult, more so as neither of them explicitly states the conclusion they have drawn (treating it as obvious), and it is only referred to in passing later in the text. Although Ada's mother keeps a wedding photo dated August 1871, eleven months before her birth, they find in a box in the attic a newspaper announcement dating the wedding to December 1871; and furthermore that Dan had been abroad since that spring, as proved by his extensive filmreels. Hence he is not Ada's father. Furthermore, they find an annotated flower album kept by Marina in 1869–70 which indicates, very obliquely, that she was pregnant and confined to a sanatorium at the same time as Aqua; that 99 orchids were delivered
