Virginia Giuffre completed “Nobody’s Girl” four years before her death in April. It will be released by Knopf on Oct. 21, the publisher announced Sunday.

Knopf, a subsidiary of Penguin Random House, will release the memoir on Oct. 21 for hardcover, ebook, and audiobook purchase. Giuffre collaborated with writer Amy Wallace to compile her story. Giuffre emailed Wallace in the weeks before she died, saying she wished for the memoir to be published regardless of her circumstances, according to Knopf.
