Oct. 5, 2011— -- After four years in prison, Amanda Knox -- the Seattle student convicted of murdering her roommate while studying abroad in Italy -- is now free, and back home with her family in Seattle.

ABC News has the full story in its new video eBook, THE AMANDA KNOX STORY: A Murder in Perugia, available for sale on the iBooks, Kindle, and Nook eBook stores.

THE AMANDA KNOX STORY combines the best of ABC News coverage of this polarizing case whose twists and turns have attracted attention across the globe.

Knox, a young American student from Seattle, had only just begun her study-abroad adventure in Perugia, Italy, when she was arrested for allegedly killing her British roommate, Meredith Kercher.

Knox, who had no criminal record and no history of violence, was later convicted of the murder, along with her then-boyfriend Italian student Raffaele Sollecito, and another man.

Many believe Knox fell victim to an overzealous prosecution and anti-American sentiment. Some legal experts in the United States say that if the murder had occured here, the evidence against her would not have been enough to bring her to trial. Others contend that the DNA and other evidence tells the whole story; she is a conniving killer.

An Italian judge and jury held Knox accountable, convicting her and her ex-boyfriend in December 2009 for the killing, sentencing Knox to 26 years behind bars, and Sollecito to 25 years. Another man, Rudy Guede, a drifter from the Ivory Coast, has also been convicted. He has exhausted his final appeal.

On Monday, after independent experts re-evaluated the DNA evidence in the case and determined that it was not credible due to the fact that the manner in which it was collected, stored and analyzed was below international standards, an appelate jury overturned Knox's and Sollecito's guilty verdicts. Knox's family swept her back to Seattle Tuesday.

Taking readers deep inside this fascinating mystery, THE AMANDA KNOX STORY is packed with video -- including exclusive interviews with the Knox family and Knox's own home video, as well as rarely-seen photos, and documents from the case files. This unique book also includes excerpts from Knox's prison diary, and a video foreword and endnote from 20/20 Anchor Elizabeth Vargas, who has been covering the case since 2007.
