Lisa Marie Presley's posthumous memoir shares new insight into the day her father, Elvis Presley, died at Graceland, writing "my life as I knew it is completely over" after her father died at age 42 in 1977.

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.

There were so many times that I found him down on the floor or unable to control his body very well,” Lisa Marie Presley writes of her father, Elvis, in her posthumous new memoir.
