I have just uploaded the paperback version of Life in the North: An Apocalyptic LitRPG.
There won’t be a paperback version of A Healer’s Gift or An Adventurer’s Heart but once I am able to create a box set for that, I’ll create a paperback version. Since each of those books are only 40-50k each, I figure a full paperback of all 3 would make sense.
The other thing is the cost of producing paperbacks. Just to get the backcover images, it cost an additional $100. Now, knowing that each 1,000 eBooks I sell, I (might) sell a single paperback copy, you can see how it would take a VERY long time for covers to be paid back.
Thus, only producing for the System Apocalypse series for now.
