Lisa Marie Presley's much-anticipated book is around the corner, where she reflected on her life's key moments. 

Unfortunately, she died before completing her memoir From Here to the Great Unknown. Her daughter Riley Keough, meanwhile, picked up the unfinished chapters and wrote them full.

"Wherever possible, I wrote it exactly as she said it," the 35-year-old penned in the book. "In other cases, I’ve edited my mother’s words for clarity or to get at what I know was the root of what she was trying to convey."

"What mattered most to me was feeling like the end result sounded like her, that I could instantly recognize her in the pages, and I can."

The Under the Bridge star said the tapes, which her late mother left in her memories, were so important in finishing the book.

“The tapes are an incredible portrait of the force of nature that she was,” she told People. “Depending on the day and her mood, she can sound locked-in or distracted, vulnerable and open or annoyed and closed off hopeful, angry, everything. You hear her in all her complications.”

In the meantime, From Here to the Great Unknown will hit the bookshelves on Oct 8.
