Disclaimer: this is not a review of the game's rules.
I didn't even get to the game part because this book is just awfully presented and I grow more enraged every time I pick it up.
Chapters should be concise and focused, instead they're broken into many numbered paragraphs and sub-paragraphs that interrupt the flow of reading.
Some fundamentals aren't explained in detail (ie: movement).
Some rules are not even used in the game but explained nonetheless (ie: star powers).
Some rules that could be explained in one simple sentence are broken into bullet points and examples (ie: activation roll).
Tables aren't organized.
The book is littered with long and repeated explanations of things that shouldn't be explained at all (ie: how to use a table and my most hated feature of all: "Here's how we do it:" is written 63 times. A rulebook is exactly that, an explanation of how things work).
Several fundamental rules of the Chain Reaction system are explained backwards.
I bought this book beacuse I thought that the authors might have put more effort than in the free Chain Reaction pdf (which suffers from the same issues), and worked on the criticism towards previous products (saw complaints similar to these of mine, several times online). No chance.
I want to believe that there's a good, solid game behind the Chain Reaction system, but I might never really know because I can't get to that. The book works against my patience as a reader.
