Amanda Knox, an American woman cleared of murdering her British housemate in Italy in 2007, has signed a book deal.
Publisher HarperCollins said she will "give a full and unflinching account" of both her arrest and trial.
The deal is reportedly worth $US4 million for world rights and is tentatively scheduled for early 2013.
Ms Knox, 24, was cleared in October of killing her British housemate Meredith Kercher, of south London, in the city of Perugia.
The BBC reports an appeal court overturned her conviction and that of her former boyfriend Raffaele Sollecito, who had also been found guilty of murder, after doubts were raised about the gathering of DNA evidence.
However, prosecutors have launched an appeal against the acquittals.
