I'll get the ball rolling.
At the moment I am reading 'The Unabridged Journals of Sylvia Plath' and a biography on that very same woman: 'The Death and Life of Sylvia Plath'.
She is the most interesting, intelligent, genuinely real poet/author that I have ever come across and I have never so intently gone about studying someone before without it being necessary for educational or work reasons. The journals are so frank and yet so beautifully written - I just want to underline every sentence and remember it forever. Plath also wrote my favourite novel: 'The Bell Jar', a book that I feel can never be trumped in it's portrayal of the haunting, twisted but yet wonderful process that we call 'being alive'.
