Query: Worst book I have ever read! Do not read this "book"

This is without doubt, the worst written book ever.EVER. AS Byatt writes with extremely pretentious language. She uses words that only the best dictionaries have. Within the first 160 pages, absolutely nothing happens. The mindboggling slowness of these 160 pages is only exceeded in incompetence in the non-stop interruptions of her story, with bad poems and bad fairy tales.The book is so badly written, with so much unneccessary padding, and so many unneccessary interruptions. ... and while there may be pretentious values of the book like "postmodern" techniques and all that, it is a very slow, poorly written, difficult book. There is no great meaning or message. A twist, but, who cares? 500+ pages of agony
