This is my problem. I am not reading chapters on a regular basis because of work, and now I am locked in a cycle of unlocking chapters that I have already read, or I am trying to bounce ahead and end up unlocking a chapter a chapter or two ahead of where I should have been.
After struggling with this, I am just not successfully reading any WUF series anymore. Once in a while, I will try to unlock a chapter or two, then remember the futility of it, give up and wander off.
