Book tells of jailed Amanda Knox's 'stubborn naivety'

Amanda Knox, the American convicted of murdering a British student in Italy, is quoted as saying in a new book she was "guided for too long by stubborn naivety which created confusion".

In a book recording conversations with an Italian lawmaker, Knox acknowledges she was "not always understandable".

She also talks about her aspirations to become a writer, marry and adopt children.
