Amanda Knox, who was freed last year from an Italian jail after being imprisoned for four years on murder charges, has signed a book deal with HarperCollins that will pay her close to $4 million, EW.com reports.

Knox, 24, was cleared four months ago of charges that she killed her roommate, Meredith Kercher. Prosecutors in Italy continue to push to keep the case alive, but Knox has since returned home to the U.S. and most observers consider it unlikely that she will be returned to Italy.

Rights to her story, which will be based largely on a diary she kept during her time in prison, became the subject of a bidding war in the publishing industry.

HarperCollins issued a statement saying: “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. … 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.”
