This is great fun - time after time the authors would throw out an example and I'd think: yep, that one was in book X. Bad characterisation, bad plot devices, bad dialogue, even bad query letters - they're all in here. The humour might get a little tedious for some, since it's all a bit over-the-top, but I enjoyed it. Usually I don't read this type of book thoroughly, just skim the best bits, but this one I read from cover to cover. Highly entertaining.
