I'm not sure as I haven't read it. But it could be about loss, given the title 'The Bitter End'. Maybe it's about the end of a relationship, a way of life, or a dream.
I'm sorry, I haven't read this novel specifically, so I can't provide reviews directly. But you can try searching on Goodreads. There are usually many readers sharing their thoughts and reviews on books there.
