Lisa Marie Presley's raw memoir "From Here to the Great Unknown" is out now. Ahead of Oprah's Riley Keough interview, these are the biggest reveals.

During a conversation with Oprah, Riley Keough reflected on her family’s legacy, sharing memories of her mother Lisa Marie Presley and her late grandfather Elvis, including Lisa’s recollections of Elvis’s struggles and her tragic final memories of him when she was just nine.

Riley Keough was quick to agree to help complete her mother’s memoir. She thought they’d write it together, reflecting on her extraordinary upbringing and life, but it became a much greater responsibility after Lisa Marie Presley’s sudden death in 2023.
