Yes that's exactly how I felt! The book was Expectations by Anna Hope which was quite an emotional read for me. Was all tucked up on the sofa with snacks and before I knew it, I was onto the sodding Acknowledgements page. It's made me feel a bit put out that's how my journey ended with that book.I can't stand it when that happens on Kindle, I actually wrote to Avon Books and complained about it. They responded and wrote a long message about Kindle clicks = more money or something. It is so annoying, I would cosy down and think I have 20% of a book to go but no, it is over without a proper goodbye.
