Overall, the book is structured in a logical and clear manner and is written in precise and concise academic language. The fact that the volume under review is not bulky (i.e. only ninety-five pages in length) does not detract from its value. Readers would feel like sitting vis-a`-vis with the authors while reading the book, and therefore it could be used as either a classroom text or a supplement reading. Nevertheless, the book may require readers to have basic statistics knowledge and data analytic techniques. Particularly, it may appeal to those who specialize in quantitative linguistics, computational linguistics, NLP, corpus linguistics, corpus-based translation studies, and so forth. Those who attempt to employ quantitative approaches to investigate negative and speculative language in other domains would also find this book useful. For these reasons, Cruz Díaz and Maña Lópezs present work is a great contribution to the field of quantitative studies and is well worth recommending. -- Haoda Feng, Bohai University, P. R.
