First, I felt the book was a bit short. Sitting at ~50k words, I wanted to bulk it up a little bit. Not add in fluff, mind you. Any one who reads the series knows I am not one for fluff. I am prone to under-describing things, so I'm taking cares to make sure I don't do this too much.
Second, I have come up with something that I want to think out completely before moving on. It's a decently important concept that will play a factor in later books, so I want to make sure it makes sense and works the way I want it to. If you are a reader of this series, you know how much I bounce off ideas from previous books and work with them again. I do this in part to tie the world better together and to close up smaller story arcs. Think back to the cabin scene in book 1 and how it came up a few times later.
Third and the most time consuming. I'm studying for a test. No, not a college exam. An IT certification called Network+. Since my options are to either pay $1000 to go take a class, and miss work for 2 months, or pay $250 to just take the test, I've opted to just take the test. The downside is that I am on my own to learn this stuff. Luckily, I've been doing networking stuff for a dozenish, to the point of building my own routers (I tend to kill store bought ones in under a year), so it's just a lot of memorizing of abbreviations and terminology, but I really don't want to fail a $250 test. So, I'm busting my butt to do this right. Sorry folks, real life before my glorified hobby.
Not that I don't love you folks! <3
