Query: Not up to Byatt standards

I have read the first three novels in the series perhaps five times a piece. I have lived deeply in the lives of the characters. My knowledge of English literature and history has added depth because of those novels.Thus, I must admit to deep disappointment in the Whistling Woman. It seemed Byatt just wanted to end the lives of the characters as quickly as possible. The plot was shaky and not quite believable. For me there was no closure. I hate to admit to identifying so greatly with fictional people, but it seemed Byatt had forgotten the lives she created and was thoughtlessly butchering the intricate world she had built.The final novel does not contain enough social and academic theory to satisfy the thirst Byatt so thoroughly quenches.If you love the series, don't read the final book. Make up your own ending. Trust me, it will be much better than the hack job Byatt has handed us.
