I've been working on this one for quite a while now, months in fact. Whoever knew that formatting books for print would take so long? Well, it's mostly because I've been fitting it in around writing them, which definitely takes a while.
If you're someone who still prefers to read in print, you can now buy the whole series. Prices vary because they're based on the number of pages in the books. I've tried to keep the costs down as much as possible, but I have less control over print books than I do over ebooks.
Hopefully now that I have things figured out, the newer books will come out in print as they come out in ebook form.
