Amanda Knox, the American college student acquitted last year of killing her roommate in Italy, has inked a book deal with HarperCollins said to be worth nearly $4 million.

The as-yet-untitled memoir, scheduled for release in 2013, will discuss Knox's legal woes and the international drama that surrounded her case. Knox spent four years in an Italian jail for allegedly killing her roommate, Meredith Kercher, a British exchange student, with her former boyfriend, Raffaele Sollecito. An appellate court overturned the 2009 convictions, and Knox moved back to her hometown of Seattle after being released from prison in 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.

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.

Here are five things we want to learn from Knox's memoir:

Relationship with Raffaele Sollecito

Knox was 20 years old when she went to Italy to study abroad and commenced a relationship with Italian Raffaele Sollecito. How exactly did their relationship begin? They hadn't been together for very long when Meredith Kercher was found murdered. After his release, Sollecito told an Italian magazine that he and Knox were still in touch, The Daily Telegraph reported. What is the status of their relationship today?

How she was treated in prison

Knox told reporters in December 2009 that she was treated kindly by prison guards, but that didn't seem to always be the case. A CBS News report revealed that Knox was allegedly sexually harassed by a prison administrator who would take her to his office and say a number of inappropriate things to her. Knox's parents were quoted in the Sunday Times -- and later accused of libel -- as saying that their daughter had not been given an interpreter, had not received food and water and had been physically and verbally abused, according to a CNN report.

How she kept busy in prison

Knox had access to a hairstylist, television and ping-pong, according to a People magazine report. She also wrote a screenplay for a music video for an Italian band that played at the prison where she was held, according to a Daily Mail report. What else did she do in prison?

Why she did cartwheels, among other things

Knox was described as behaving strangely while waiting to be questioned by police after Kercher's body was found, The Daily Telegraph reported. This alleged behavior included doing cartwheels and yoga. Knox also got flak for wearing a T-shirt that read All you need is love the day she was convicted of murder.

Did she expect to get off?

Friends and family described Knox before the case as an optimistic young woman, but also one who disliked conflict, according to a report in the Los Angeles Times. How her reported positive attitude helped her fare in prison remains to be seen. With what she knew of the case, did Knox ever expect that she'd be released to return home to the U.S.?
