Meredith Kercher's family has no interest in reading Amanda Knox's book, the sister of the murdered British student has said.
Stephanie Kercher's comments came after Miss Knox appeared in her first television interview since being freed from an Italian prison to promote her memoir.
She said she would like to visit Miss Kercher's grave, but only with the permission of the Kercher family.
Stephanie Kercher said in a statement: ''We are not interested in this book, as well as all the others regarding the case and we will not be reading it.
''The Italian legal system still has an appeal procedure underway and as a result a new trial will be heard. The sentence can still be overturned."

She did not address the wish expressed by Miss Knox, but said: "I have no doubts that even on the other side there is a story of pain and loss and of enormous lack of trust, but on the other side there is also one of hope and an opportunity of life.
"Something that Meredith will never have and something that we will never share with her. Meredith is the victim in this tragic case."
Italian prosecutors say Miss Knox and her then-boyfriend, Raffaele Sollecito, killed Miss Kercher, 21, in a drug-fuelled sex game along with another man in 2007.
She has always denied the accusation.
Her murder conviction was overturned in October 2011, but in March an Italian court ordered a retrial for both her and Mr Sollecito, 29.
Miss Knox says she is considering a return to Italy for the retrial, even against her lawyer's advice.
"My lawyers have said that I don't have to and that I don't need to. I'm still considering it, to be honest," she told USA Today.

"It's scary, the thought. But it's also important for me to say, 'This is not just happening far away from and doesn't matter to me'.
"So, somehow, I feel it's important for me to convey that. And if my presence is what is necessary to convey that, then I'll go."
Miss Knox's alibi rests on her claim that she was at Mr Sollecito's house on the night of the murder, and not at the Perugia flat she shared with Miss Kercher.
But during a police interrogation she said she was at home with Miss Kercher.
In the interview with ABC News' Diane Sawyer, she insisted that initial claim was the result of her "breaking down".
"I didn't confess. I was interrogated," Miss Knox told ABC News. "(The police) acted like my answers were wrong, they told me I was wrong, that I didn't remember correctly, that I had to remember correctly, and that if I didn't I would never see her family.
"I can only describe it as breaking down, I didn't know what I remembered and what I didn't remember anymore. I was incredibly vulnerable at that time."
As she expressed her desire to visit Miss Kercher's grave, she said: "Eventually I can have their permission to pay my respects at her grave and I would also like them to know that she talked about them to me."
Miss Knox insists she was at Mr Sollecito's home on the night in question
In the memoir, which came out on Tuesday and is called Waiting To Be Heard, she writes about how she also considered suicide while in prison.
Miss Knox insists in the interview that she did not leave Mr Sollecito's home.
"We stayed in, had dinner, we watched a movie, we smoked, we had sex, we were together.
"We just hung out together, we talked, we talked about his mum, we made silly faces at each other. We stayed in the whole night."
The 25-year-old said she returned to the home she shared with Miss Kercher the next morning, but despite the front door being wide-open and spotting blood on the sink she took a shower.
"At the sink when I was taking out my earrings I noticed there were speckles of blood. But speckles, a few drops."
She said that when she got out of the shower she noticed a bloodied bath mat, adding: "I thought it was strange."

She returned to Mr Sollecito's home, and says she told him of her concerns after breakfast. He called police, who discovered Miss Kercher's body.
"It never occurred to me that I would ever be considered a suspect. Ever."
Miss Knox denied claims there had been any tension with Miss Kercher in the run-up to her death.
"It bothers me when people suggest that she wasn't my friend," she said. "I was stunned by her death, she was my friend."
During her original trial, much was made of Miss Knox's apparent lack of grief following Miss Kercher's death.
Miss Knox said she "could have been more sensitive" but said people deal with grief in different ways.
