Amanda Knox signs book deal with HarperCollins

(CBS/AP) Amanda Knox will soon tell her side of the story in a forthcoming tell-all book- the 24-year-old has just signed a deal with HarperCollins.

The former exchange student, who was imprisoned for four years in Perugia, Italy, facing murder charges for the murder of her British roommate, has not publicly discussed her ordeal beyond a brief expression of gratitude upon her release last October.

"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 said in a statement Thursday.

"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, currently untitled, is tentatively scheduled for early 2013.

Financial terms were not disclosed, but an official with knowledge of the negotiations said the deal was worth $4 million for world rights. The official was not authorized to discuss the negotiations and spoke to The Associated Press on condition of anonymity.Over 20 publishers were interested in the book, with received bids from seven publishers at a recent auction.

The struggle for Knox may not be over: Earlier this week, Italian prosecutors asked the country's highest criminal court to reinstate the murder convictions of Knox and her former boyfriend, Raffaele Sollecito.

Sollecito and Knox were both charged in the Nov. 1, 2007, stabbing death of Meredith Kercher, a 21-year-old British student who shared an apartment with Knox in Perugia.

The appeals court in October said the guilty verdicts against the pair were not corroborated by any evidence, and that the court hadn't proven they were in the house when Kercher was killed.
