At first I thought it was overpriced, but take a look and compare any technical book with packed with this much information. There's tons of information to digest and make notes on. Whether you're interested in pyrotechnics, understanding the chemistry of different compounds to use in rocket motors or fireworks. It's not meant as a how-to on either but the understanding of why certain chemicals are or are not mixed together, how they react in different ways. It will hopefully help you to be careful if you attempt anything along these lines. I for one glad I bought it and would have paid more now that I know how much information is in it.
