So I accidentally created a novella printed into the shape of an A4 graphic novel impostor, ha! I admit this was not expected and I only became aware of it after receiving the review on the book’s Amazon page.
This is very good to know! Now I can check the settings and find a way to fix it. This is why constructive criticism is amazingly helpful.
In a way I kind of like the size as you can see the inner illustrations very nicely as they are good quality (as well as the cover). Also the material the book is made from is very satisfying to hold. Nonetheless, the book was not created for this size.
