Well, it's been a while coming, but I finally released an electronic version of Covenant.
You can currently download the PDF at RPGNOW for a $10 price tag. This is half what the book costs, so you're getting plenty of goodness for your e-buck.
The PDF also contains all the errata and a few extra tweaks. Nothing major was added, but if you own the book, drop me and email (matt / at / realms / co / uk) and I'll hook you up with a PDF too. Gratis.
