I made a few updates and error fixes to book 2 which I've just now uploaded to both Smashwords and Amazon.
Going forward, I've updated the header for each first person POV perspective so that it's a larger size and easier to follow (especially since some perspective changes occur within a chapter on occasion).
Books 3 and 4 will have the same updates done, but the new versions won't be up until I've tackled any and all errors.
I'd like to try to get everything done in one turn because Amazon's delay for updates/changes can take well over a day.
Keep checking this page for news and future announcements. In fact, there will be a special announcement on Tuesday!
