In 2007, Amanda Knox was arrested for the brutal murder of her flatmate while studying in Italy - and it was a case that captured international attention.

Amanda was found guilty, convicted of the murder and spent four years in an Italian prison - but she was later found to be wrongly convicted.

10 years after she was officially exonerated of the crime, she's told her story in her new memoir Free: My Search for Meaning.

"I was immersed in a very restrictive environment...it was really important, for my sanity, to develop a sense of place and purpose."
