Query: Dullest Book I've Ever Read!

As I read reviews posted by other readers, I wonder if they even read the same book I did! Each time I set it down, I had to force myself to pick it up again, just because I really hate to leave a book unfinished. The characters are wooden caricatures, the dialogue is unrealistic and just dreadful, and the whole story is flat and dull. I could not more strongly urge you to find something else, ANYTHING else (the ingredient list on the back of a shampoo bottle, for instance), to read... but I'm obviously in the minority here.
