I agree that it covers a lot of topics, many of them are important. They actually include much more topics in the second edition than the first one. However, the authors seldomly discuss one topic more than a page. It's like reading abstracts of papers. So if you already know the stuff, you don't need this book. Just go for some papers (papers are at least up to date). If you don't know anything about Monte Carlo sampling, this book is not going to help you too much. So don't waste your money on this book. Newman's book or Frenkel's book is much better.
