3 stars for this book for me until the last 70 pages redeemed the first 700. So I suppose this is the purpose: the journey seems long and pointless until something unexpected happens and the reader knows that the journey was necessary to get to the surprising destination...
I guess I can't help but wander after reading this book, which is full of self-talk and frantic mental wanderings, jumps, spirals. And way more vomiting than any other book I've read. There were times when I hated it. But I loved it in the end, which is what counts, I suppose.
It's a very ambitious novel. Tartt set out to make a big statement about good and bad and the lines between, and bad coming from good and good coming from bad. She explicitly states this near the end, which perhaps shouldn't have been necessary, but it did help. As much as I fought her as a reader, I did enjoy the excellent writing and the arc of the story.
