Echelon is one of those novels that is quite fun while you're reading it and then instantly forgotten once you've finished. It's not bad for what it is - all high-octane, densely plotted stuff packed with boat chases, shootouts, conspiracy and subterfuge for those who like that sort of thing. The problem is, there isn't enough here to make the novel stand out on its own two feet as something unique. It's all very Neuromancer crossed with James Bond without being as good as either. In fact, Conviser's depictions of 'the flow' aren't nearly as convincing as Gibson's portrayal of a digital world and that was written well over twenty years ago before such things as the internet even existed!
You would think that a novel filled with this much action would make me care about what's going on to the main characters, but unfortunately beyond all the explosions and fight scenes there is very little at the heart of this book. A lack of core characters makes it obvious away who the real bad guy is. And a lack of subtext and moral questioning about the implications of Laing's actions leaves the book feeling flat and bland. Personally, I think a much better novel could have been achieved if Conviser had spent more time going into the implications of what he shows us. For example, what's it like coming back from the dead? Was there an afterlife? If not, how does that affect someone's take on life? Laing's attitude of constantly going around like a man with a death wish just seems wrong considering he's already died once.
As said, this isn't a bad book. It's a solid example of its genre, well paced and with consistent writing. But more than anything else, it just didn't excite me very much. To be blunt, I found it hard at times to care about what was happening and quickly got bored while reading it despite the rate at which I was turning those pages. That, more than anything else, is the biggest criticism I can level against this book.
