Amanda Knox's 'Waiting to Be Heard' Book Cover Released, but Not Book

Nov. 28, 2012— -- It has been more than a year since Amanda Knox was cleared of murder charges in an Italian court, and the Seattle woman has kept largely silent since then, working on a book about her ordeal.

The cover of the book was released today, along with the title, "Waiting to Be Heard," but not the book.

In the photo, a casually dressed and unsmiling Knox stares straight into the camera.

Knox's publisher, HarperCollins, said the memoir would be released April 30, 2013, two months later than originally scheduled.

Italian prosecutors, who are appealing Knox's release from prison and want her murder conviction reinstated, are due to appear in court March 25.

Knox, now 25, was convicted in December 2009 for the 2007 murder of her British roommate, Meredith Kercher, in the Italian city of Perugia. Knox's Italian boyfriend at the time, Raffaele Sollecito, was also convicted.

The pair were freed from prison four years later, when an Italian appeals court threw out the guilty verdict and criticized the prosecution's case.

Knox's book, for which she reportedly received an advance of $4 million, will be the latest volume about the case.

Earlier this year, Sollecito published a book titled "Honor Bound, My Journey to Hell and Back With Amanda Knox," about the conviction, appeal and his time in prison. The two reunited briefly in Knox's hometown of Seattle during Sollecito's book tour. He said they have kept in touch since their prison release through email and Skype.

In addition to Knox's and Sollecito's books, journalists have written several other books about the Knox case, and a Lifetime movie, "Amanda Knox: Murder On Trial In Italy," aired last year.

A third person, Rudy Guede, was convicted in a separate trial and is serving a 16-year prison sentence.
