All things considered, I was a little disappointed with this book. I was hoping it would focus on Negreanu's unique style of poker and that it would present ideas not yet covered by the other great poker books (like the Harrington series of books on tournaments and cash games). But it's a 485 page book and Negreanu doesn't even pen a word of it until the last 200 pages.
There are 5 chapters before Negreanu's, each written by a different pro: Evelyn Ng, Todd Brunson, Erick Lindgren, Paul Wasicka, & David Williams. Ng's chapter presented an interesting strategy for beginners that made a lot of sense to me and that I hadn't heard of before, which was good. But the other 4 chapters by the pros were a waste of time. Brunson, Lindgren, Wasicka, & Williams all wrote about very basic concepts that I'd heard of a million times before.
Brunson's chapter was on cash games, but he didn't even scratch the surface of cash game strategy in the way that Harrington on Cash Games did. He spent an entire chapter talking about re-buying, not bluffing, & trap hands.
Lindgren's chapter was about online play. The major flaw with that chapter was that it was written for players that cut their teeth playing in casinos and are now moving online. In reality, I think most of us start online and work our way towards casinos if we succeed online, so the whole chapter felt "backwards". He provided a little more actual in-game strategy than Brunson, but not much.
Wasicka's chapter was about short-handed tables. Outside of Ng's chapter I found this chapter the most useful. Wasicka presented some ideas which were new to me and even the ones that weren't new were at least logical and presented well.
Williams' chapter could have been written in 1 sentence: "Mix up your play so your opponent can't read what you've got." It's the first rule of poker to not let yourself fall into the trap of being predictable and Williams some how rambled on about this for a whole chapter.
With all that being said, Daniel's chapter was great and I thought it was good enough to stand on its own. About 200 pages in length, he describes in depth his small-ball strategy, the math that makes it work, and how to master it. He guides the reader through starting hand selection and position all the way thru flop, turn, & river play, making lots of easy to understand analogies along the way. Although I think the rest of the poker world as caught on to Daniel's methods since his immense success in 2003 & 2004, this strategy is a useful weapon for any poker player to have in his arsenal. Daniel's strategy, when properly employed, should allow the reader to pick up lots of uncontested pots and should keep pots small unless the reader has a big hand.
Taken on a chapter by chapter basis, I'd give the following ratings:
Ng: 4 stars
Brunson: 1 star
Lindgren: 2 stars
Wasicka: 3 stars
Williams: 1 star
Negreanu: 5 stars
But as a whole, with all the fluff in there, I'd give the whole book just 2 stars.
