AMANDA KNOX harrowing tell-all memoir coming – in her own words – the whole, shocking story!  

The brunette beauty, 24,  from Seattle, Washington whose murder conviction in Italy and eventual acquittal on made headlines worldwide has inked a deal with HarperCollins for $4 million to tell her story.

Knox who was imprisoned for four years in Perugia, Italy, has not publicly discussed her ordeal.

"Knox will give a full and unflinching account of the events that led to her arrest in Perugia and her struggles with the complexities of the Italian judicial system," HarperCollins ballyhooed the book deal.

"Aided by journals she kept during her imprisonment, Knox will talk about her harrowing experience at the hands of the Italian police and later prison guards and inmates.

“She will reveal never before-told details surrounding her case, and describe how she used her inner strength and strong family ties to cope with the most challenging time of her young life."

The book's due in 2013.
