I was looking for an introductory text that was current and that would cover the most popular approaches. I didn't want something directed at the popular level (little or no math), but I also didn't want a text that would go into agonizing analysis of every plasma instability under the sun. There are many fine books on plasma physics (e.g F. F. Chen's "Introduction to Plasma Physics and Controlled Fusion"); that is not what I was looking for and that is not the emphasis of this text.
This covers the basic physics and explains the basic concepts behind several of the more popular fusion approaches. The reader should have college level physics and calculus to get the most out of this book. I found it useful but not comprehensive (you can only fit so much in under 300 pages). So if you want to know the fusion cross-section of, say, p + B reactions, you'll need to locate other information sources. But you will find reaction cross-section tabulations on d + t, d + d, etc. reactions as a function of energy.
