Before her sudden death in 2023, Lisa Marie Presley was working on a memoir with the help of her eldest daughter, Riley Keough. After her passing, Riley took it upon herself to finish her mother’s project, relying on hours of audio tapes that Lisa Marie left behind. The result is the posthumous memoir “From Here to the Great Unknown,” which looks at what it was like to grow up in the whirlwind of celebrity around Elvis Presley and Graceland. Riley joins Tom Power to explain why she felt so strongly about finishing her mother’s story, plus, she reflects her own legacy as Elvis’ eldest granddaughter.
