This book by Mr. Brook deals more with theory and presentation techniques than with effects. The effects are quite simple, basic if you want, and are just tools to practice the theoretical ideas put forward in the book.
These ideas come from psychology and NLP and the author says should be used to increase our performances. While some of these are interesting, I don't agree with all of them. For example, Paul talks about "mental misdirection", in the form of asking a question to a spectator and do the "dirty work" when she's thinking about the answer. Sadly, this technique is not general enough like the "attention control" (T. Wonder) but it is rather suitable for just one spectator (the rest of the audience isn't involved with the question, and they may get the "move").
The text is also rife with grammatical errors (the syntax is correct, though, thanks to spellcheckers in word processors) which gets annoying.
