To Hell's Heart is now available in print.
Crimson Worlds VI: To Hell's Heart
I know there are some dead tree guys among you, so I'm sorry it took a few extra days to get this edition out.
The audiobook version should be available around the end of the month. It is completely finished and submitted to Audible.com, but they usually take a couple weeks.
Lastly, for any of you looking for the Kobo edition of the ebook, I cannot explain why they have not finished processing it yet. It was sent to them at the same time as the other retailers. Hopefully it will be live soon.
And thanks to all for the comments and reviews!
