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.

I had thought that maybe we wouldn’t do anything until we got married, but he said, ‘I’m not waiting!'” Presley wrote in “From Here to the Great Unknown.”

Elvis Presley, the King of Rock and Roll, died unexpectedly in August 1977 at his Graceland estate at the age of 42. While the world was devastated by the sudden loss, Lisa Marie, who was just nine years old at the time, had a feeling that her father's days were numbered.
