I'm about halfway through my re-read of Mind Games. I'm taking notes along the way, as I mentioned before, but I'm also correcting whatever goofs I find in the manuscript. It's pretty clean, but it's not perfect. I think I've found three usage errors so far, as well as one minor inconsistency. Once my re-read of this book is done, I'll upload the corrected version to the retailers.
I'm anxious to start the next draft of book 4. I also need to allocate some time to cover design. The covers for 4 and 5 are done, but I still need to do the last two, and these things take me a long time, so I have to start early.
