Here's the cover for Chapter 13, which you can read in its entirety, over at yearofthegodfox.com! It's a for-pay comic, but there are free preview pages for all the chapters, and you can read the prologue for free right here.
This concludes Book 3! Book 4 goes live on Friday, April 25th! Be sure to check it out!
You can also follow the comic's official tumblr for more updates and extras.
Enjoy!
P.S. I've been asked many times if the fee is a subscription or one-time charge. The answer is: it is a one-time charge! You make an account, pay for whatever amount of content you want, and you get access to that so long as the site exists. You also gain the ability to comment on all the material you've paid to access, so you can leave spoilorific comments on the relevant pages—where they won't really be spoilers. ;)
