There's a nice combination of jargon-free 'how to' editorial that features guides for planning and execution, coupled with numerous case studies.
Interestingly, the book chooses to focus much more heavily on marketing on the internet than any other form of direct marketing.
Considering the relatively low level of web activity that the voluntary sector is actually engaged in, I found that rather surprising.
I liked the fact that the book encourages marketers in the voluntary sector to view their 'target audiences' as customers. Once you've made that mental leap and start adapting what you have to offer to specific external needs, then you move into exactly the same realm as any other commercial company.
Of course, in trying to be so inclusive, the book cannot offer any more than an overview of the opportunities and relative merits of each part of the marketing mix. However, for small and medium-sized charities that are just starting out, it's a very useful and informative read.
