[Q]: Plate Tectonics as told by those that assembled the theory . This is a highly informative account of both the ideas that led to the development of Plate Tectonic theory and the concepts of how the earth works. The book is engaging to read and is understandable to an audience at the level of Scientific American. I am using it as a required text in my course at Columbia University titled "Plate-tectonic theory and its geological corollaries". For those fascinated in how the human mind puts observations together to build ideas and then test them, this book is first rate. Each chapter is crafted by a different researcher describing his or her contribution to the over all theory. The reader encounters brilliant and original ideas discarded by peer review, scientists peeping over each other's shoulder, the rush to the goal line to publish first, competition for access to key data sets, a last minute conversion from the static earth perspective, and the thrill of exploration at sea. The authors presents a wonderful history in Chapter 1 of the intellectual passage from the first inkling of continental drift in the 16th century to the breakthrough in 1966-1968 of the full-blown theory of rigid lithosphere paving stones and narrow plate boundaries
[A]: POS

[Q]: Didn't care what happened to the main characters . I bought this book so I'd have something interesting to read during my son's tonsillectomy last fall. I was hoping to enjoy the torrid love scenes in it! I got half-way through the book, and it bothered me so much (my own issues getting in the way?), I put the book away. I felt Anna was emotionally neglecting her daughter, Molly, while involved in her lustful dysfunctional relationship with Leo. I didn't like any of the main characters, including Molly---all too unrealistic. But I picked up the book yesterday and finished it. The book was too flat! Though I don't think she was a BAD mom, she certainly exercised poor judgment (and for what? Like Leo was a good catch?)! I wasted my time (I don't read books very often) on this story. Yet I did read the whole book, hoping it would get better, so I'm giving it 2 stars. I didn't think I'd get any more of Sue Miller's books, but other reviewers said she has better novels
[A]: NEG

[Q]: Wow, how did this ever get published? . This is just a REALLY bad book. First I blame James Patterson, but I really REALLY blame his editor. What editor worth his salt would allow this mess to be published? The villains are so grotesque as to be almost cartoon villains. Just - over the top. The plot line is unbelievable. Aside from Alex Cross and the two villains, nobody in this book gets more than a few pages before they disappear forever. Alex Cross spends more time eating meals than using the resources of the FBI to foil the villains. This is supposed to be one of those "the villains have given us a deadline before they blow up the world" type thriller but - there's no sense of urgency, and the law-enforcement agencies on the case are poorly sketched, and inept (but not deliberately written that way). I could go on and on but it's not worth the words. This book is REALLY a waste of time. I can't believe anybody published it
