The book is prose poetry. I've only read it once and I stopped trying to make sense of some passages and read/listened to it in a stream of conscious way. So I missed some parts in between. I read that Woolf re-wrote the draft multiple times. Consuming this work needs focus The prose is very evocative and the structure is really great - six characters - childhood friends - speak (or think) their inner thoughts over a period of their lifetime broken into several sections. As a reviewer Violet Wells points out in her Goodreads review, the style does away with the "usual matrix of bald accountable facts, social landmarks of achievement and failure.". It provides a glimpse of the inner thoughts of the characters.
I've also started reading Woolf's writing diaries. I'm planning to re-read the book after I'm done with that.
