This is an anti-globalisation book through and through, so don't expect any reasoned debate. If you're unfamiliar with globalisation theory, you'll need to look elsewhere. If you've looked into it, don't like what you see, and feel powerless in the face of it, then this becomes a more useful book.
Roddick's credentials in the anti-globalisation world are great - a major CEO with principles, not afraid to get her hands dirty. But Roddick is only compiling here, and although some of contributors bring something informative, some sections are paper thin, ranting, or inward-looking, like the work of an anti-globalisation in-crowd (Yes, you were tear-gassed in Seattle in 99, get over it). At times it's even rather lazy, with calls for action against 'them' that forget to mention who 'them' is. It ends up giving you a whole lot of things to be indignant about, but without quite explaining why.
Still, it's a quick read, it covers a lot of ground and serves as a good whistle-stop tour of the main issues.
