I really found this hard to read, too.
It was beautifully written, but the huge amounts of spoken word was very difficult for me to interpret (not helped by me reading it in a bad Jamaican accent, which I know was not right) and put me off the story.
I am glad I made it to the end (eventually). The last few chapters were quite gripping, and I did appreciate the story.
It was only at the very end that I started to like Janie, and to be interested in what happened to her.
