So at some point in the self-publishing process, the following passage in chapter two was changed from:

One of his arms was a few centimeters shorter than the other, as that had been the starting point of the rogue cell growth, but he had recovered and the arm worked perfectly fine. 

To

One of his arms was a few centimeters shorter than the other, as that had been the starting point of the rouge cell growth, but he had recovered and the arm worked perfectly fine. 

I have no idea where in the process this occurred, but it took me three hours to fix the error in both the print and kindle version of the text. The ability to version works is both a blessing and a curse. Once I knew the error was there, I had to fix the problem. Due to some formatting issues, this took me three hours, and I think the interior of the print version is less pleasing now. The TOC is off center and I think the spine text moved a pixel.

But at least the damn cancer is described correctly, right? I want to say I learned my lesson here and I won't edit the text again, but I know that's a lie. The whack-a-mole that is print editing is one of the best and worst video games ever, and I'm addicted to leveling up like it was Candy Crush.
