Amanda Knox, Diane Sawyer Exclusive First Interview [VIDEO]: Accused Murderer Discusses Case, Retrial, Headlines and Book

In an exclusive interview with ABC's Diane Sawyer, accused murderer Amanda Knox opens up for the first time and discusses the turmoil she has gone through. Accused of murdering her roommate Meredith Kercher with her then-boyfriend Raffaele Sollecito in 2007, Knox was imprisoned in an Italian jail until her case was overturned in 2011. But earlier this year, a retrial was ordered in Italy, sending Amanda Knox back into the headlines after her attempts to live a normal life. Her new book, "Waiting To Be Heard," reveals a lot of what happened to Knox and her interview with Sawyer has her answering the questions the world wants to hear.

With this retrial, Amanda does not have to actually return to Italy. Extradition can only be a factor if and when the Italian Supreme Court finds her guilty of her crimes. Despite this, Amanda says that hearing about the retrial "was incredibly painful."

Though surely she has not forgotten at all, she is brought back into a worl that had her imprisoned for years.

"I felt like after crawling through a field of barbed wire and finally reaching what I thought was the end, it just turned out that it was the horizon," Knox said. "And I had another field of barbed wire that I had ahead of me to crawl through."

Though she also said that, if she has to, she will fight for her case.

"If there needs to be a re-evaluation of looking into the facts, that's fine," she said. "Because facts are facts and I'm not afraid of them."

This whole case in a strange way overshadows the death of Kercher, to which Knox said: "It's not fair that there is not a satisfactory answer for what happened to Meredith, and the attention that's been taken away from her and what happened to her is not fair." 

ABC will air more clips of Amanda Knox's interview this week.
