The book is a thorough review of the differnet aspects of terrorism, and as such it fits as an undergraduate textbook on the subject. Combs reviews the history of terrorism, different types of terrorism, and how people and governmnets dealt with this phenomenon during the years.
The book is written is a clear and communicative style, and each chapter ends with several issues for indepth thinking and discussion.
The relatively small size of the book, the clarity and exhaustiveness of its coverage of terrorism make it attractive to a busy student who wishes to learn about terrorism but has very little time to spend on such study. I truely think the book merits 5 point especially compared to other material written on this subject these days.
