John Ringo has crafted a universe in which some aliens, themselves incapable of violence or, apparently, military strategy, have decided to use humans as literal "army ants" to destroy some other aliens who have been taking their worlds away from them one by one. And, of course, once the job is done and we're no longer needed...
Of course humanity has long had a history of wriggling out of binds and generally playing merry hell with expectations made of it, and in this book, we are no different. I won't spoil the fun, but it's interesting seeing Ringo deal simultaneously with High Strategy and Low Tactics at the same time, while giving us characters we can care about and follow around as they attempt to keep humanity alive.
