According to Meyer, the idea for "Twilight" came to her in a dream on June 2, 2003 about a human girl and a vampire who was in love with her but thirsted for her blood. Based on this dream, Meyer wrote the draft of what became chapter 13 of the book. She wrote from chapter 13 to the end of the novel and then backfilled the first 12 chapters, in secret, without an ideal audience in mind or the intention to publish the novel. Meyer researched the Quileute Native Americans to include their legends and traditions in the novel, though the Quileute tribe found her use of their legends offensive. Meyer joined the American Night Writers Association (ANWA) for aspiring LDS female writers. In three months she had transformed the dream into a complete novel. Her sister's response to the book was enthusiastic and she persuaded Meyer to send the manuscript to literary agencies.
