I have been a fan of Neal's for sometime. I have enjoyed a number of his works. Quicksilver is one that I did not enjoy. The only delight was in the first couple of chapters. These first few chapters were interesting and engaging. After that it goes down hill fast. While I have an interest in science, philosophy, and history I found the articulation of these wonderful subjects very much lacking in Quicksilver. The premise is wonderful, but written badly and the characters becom wooden and puppet like. It hurts to say this, because I truly enjoyed Neal's other works. Clearly, I would not recommend this book.
