NEW YORK — A memoir that Lisa Marie Presley had been working on at the time of her death will be published this fall. The book, currently untitled, was completed with the help of actor Riley Keough, the eldest of Presley’s four children.

“Few people had the opportunity to know who my mom really was, other than being Elvis’s daughter,” Keough said in a statement released Thursday by publisher Random House. “I was lucky to have had that opportunity and working on preparing her autobiography for publication has been a privilege, albeit a bittersweet one. I’m so excited to share my mom now, at her most vulnerable and most honest, and in doing so, I do hope that readers come to love my mom as much as I did.”
