We are currently in the process of buying and registering ISBNs so we can get our first volume listed on Amazon and Barnes & Noble, which will be really exciting.
This costs money, though, and we have very little. So if you want to help out:
All donations result in a free ebook. Monthly pledges on Patreon (http://www.patreon.com/freezeframefiction) result in on-going ebooks as we release them. You can also make PayPal donations recur monthly; those will result in on-going ebooks, as well.
