okay, what we have hear is a little gem that has everything from high-energy physics to high-velocity penetrator rounds.
Its easy to lump this book with a description like 'rednecks with wormholes' but seriously, i've read books with far worse premises (and execution) from supposedly more 'serious' writers.
If you like your science fiction murky, with endless introspection and the occasional smattering of psuedo-technical terms like 'hyperdrive' or 'wormhole' to place it in a 'science-fiction' setting then this book, frankly, isnt for you.
What it is, is a book with clearly defined enemy, a hero of the 'old school' with a square jaw and a multitude of skills and the application of serious amounts of firepower.
Yes, it has massive amounts of high-energy physics described inside it. Is that so wrong? I've read the book twice and i'm still fuzzy on the differences between a gluon, a muon and a quark but you know what, i'm fine with that. I still, quite easily, managed to get the gist of what Ringo was describing because there are characters in the book that dont understand the physics either and the exposition between them breaks the physics explanations up into chunks that the reader CAN understand...and by the end of it, i DID manage to learn some new physics.
so in conclusion...if you're a reader of Ringo before, there's no new surprises here except for a fascinating premise of 'wormholes', their generation, maintenance and unintended consequences.
If your new to Ringo's works, sit back and enjoy it for what it is, a tale of derring do against an implacable foe and, yes, rednecks with explosives.
