Killswitch on Don D'Ammassa

And here's a review on Don D'Ammassa's website, where he says in part, 'Easily the best of the three. I hope there’s more on their way. Most novels with this general background get caught up in the military content and forget about the characters. Shepherd manages to keep everything in balance.'

Well I don't know about 'easily', but most people seem to think Killswitch is the best.
