Cat Eldridge over at Green Man Review certainly seems to have enjoyed Orbus:

Now imagine fighting a Prador armed to, errr, its mandibles. Not a pleasant idea is it? It gets worse. Without giving away anything (or at least not too much), consider that there is something even worse than the strongest Prador. Much worse. And that being is manipulating the entire Prador race here in an attempt to make sure what that being wants to happen will happen. Throw in extremely deadly military hardware that can literally destroy planets if need be, thousand year-old post-humans who are perhaps more alien than the Prador are, and a well-armed military drone with its own agenda. This ain’t state of the art space opera of thirty years ago, or even a decade ago — it’s perhaps the best space opera I’ve ever read, and that’s saying a lot as I’ve read space opera for over thirty years now.

Thanks Cat!
