Stay Back . Reading this book was exhausting, confusing, and extremely unsatisfying. Sentences and parqagraphs ramble arround with confusing descriptions and conflicting information. Some major elements that are introduced are left hanging; never brought up again. Others are revisited ad nauseum. Barr's quirky way of describing people and places with bizarre comparisons slows down the plot and is just missleading. Although I did stay with it until the contrived end, this is the first book I ever attacked with a red pen and edited a I went along. I estimate it could have been 50 pages shorter, and have carried far more impact, without the extraneous language. I am shocked she sells well enough to have published so many books. I'd stay far away from her in the future and purify yourself by reading a clasic P.D. James or a pure and simple Sue Grafton
Output:
NEG
