On the same day as the release of her new memoir, "Waiting to Be Heard," Seattle native Amanda Knox's primetime special, which includes an in-depth, pre-taped interview with Diane Sawyer, will air on KOMO 4. The interview is Knox's first since being aquitted and re-tried by the Italian courts. 

According to teasers from the book and interview, as well as a recent interview with People magazine, Knox's experience in prison was harrowing -- cripplingly lonesome, riddled with sexual assault and violence, and consistently afraid for what was in store, Knox says that she even contemplated suicide.

With a new trial approaching, some critics are wondering why she's releasing the tell-all book. But, Knox tells People, she has good reason.

"I'm tired of speculation," she explains, "I wanted to lay myself out in a completely honest way."

The interview will air tomorrow night during ABC News Primetime at 7pm. You can see clips from the special here
