Having done some proofreading on it, I was able to read it in its final draft stage. If you are interested in my opinion, it follows:
I was very impressed with the storyline and how it unfolded. It's a meaty adventure, and should take characters on a strong mission that starts with a simple encounter of Robin Hood-esque proportions and escalates matters until the fate of the planet's future lies in the hands of the PCs. It's got heavy military overtones, of course, and even though I don't like military/mercenary games in general, I'd play this one because of the style with which it was written.
For TNE fans, I found it very reminiscent of the Smash & Grab flavor from TNE Star Vikings, with a lot of military emphasis. I definitely feel it captures the essence of the TNE material I've read so far.
But that's my personal opinion on it. I've let you know that I was involved in its production, though minimally, in case that should matter to you, but this was my general impression of it and what I sent Martin as part of my feedback. I look forward to hearing what others have to say about Early Fallen.
Happy Travellin',
