Holy crap. I purchased and downloded this for a few bucks with minimal expectations. What I got is something that could easily have been sold by Wizards for $50. This a professional-quality, full-blown campaign guide with a well thought-out story, detailed NPCs, maps, etc... I run my campaign in an existing setting of my own (well, my wife's) own creation. Fortunately, this campaign guide also includes suugestions for incorporating this campaign story into your own setting.
I'm really looking forward to getting started with this campaign.
If you're looking for a rich campaign setting for your players, or just want some inspiration for your own campaign, I highly recommend purchasing this guide.
My only wish is that they published a 5E version, but 3.5 will do.
