I have started releasing MGC content to my Patreon. My earliest beta readers have already seen the first 9 chapters of MGC 2, and soon I'll start posting it on MGC's main page here on SH. I just want to build up a backlog first so I can consistently and safely release a chapter every single day until the book is done.
Regarding MGS, I can't say how long this hiatus will be, but it isn't intended to be eternal. You can take that with a grain of salt if you like, but I don't like the idea of having an unfinished series to my name, so I do intend to finish it and then go back and edit it to something that satisfies me.
Here's Shelley's new art (from the end of MGC 1). Watch the MGC page because I have a surprise there coming sometime this week or next week for people who missed book 1 and can't afford to pay the 2.99 for it on Kindle.
