Dominic is nearing completion of The Brotherhood of Radiation after a delay, which I'll allow him to explain in his own words.
"The Brotherhood book is near to completion, but I got stalled by the release of Fallout New Vegas. Since existing material on the Brotherhood has always set the cult in and around Vegas, I felt it was cheesy to try and put it out at the same time. I didn't want to be influenced by Fallout New Vegas as I wrote, nor have people think I was ripping the game off since several chapters have to do with a post-apocalyptic Vegas. Anyway, I want to make some changes to the manuscript, and I need to finish polishing up some of the content."
Last Gambit of The Mind Masters is another story. Dominic as of right now is unable to finish this adventure. Most of it is complete. What is not complete is fully outlined. At this point I'm going to take responsibility for finishing it. This might mean I will personally finish writing it or work with other writers to bring it to completion.
So that's where things are at. I don't want to give any ETAs because I never hit them, but just know things are in the works and progressing.
