Lisa Marie's posthumous memoir From Here to the Great Unknown has been completed by her daughter Riley Keough, who used her late mother's audio tapes to help her finish off the project. The book was released this month and in it, Lisa opens up about the aftermath of her father Elvis's death when she was nine, and its effect on her.

In the memoir, Lisa Marie Presley details the toll that her legendary dad's death - when she was just nine - took on her. For the first time, she describes waking up on the afternoon that he died in August 1977 and sensing something was wrong, before running into her father's room across the hallway and seeing him facedown on the bathroom floor.

Lisa Marie had her son Benjamin with Danny Keough. The two also share daughter Riley Keough. Danny is a musician and has ties to Scientology.
