I downloaded a couple more recommended novels and now find when I return to the book I was reading before it "appears" on the last page!

Anybody know how I can go back to where I left off so I can continue to read the story without the plot being ruined by "spoilers"?

Hmm. It probably now thinks that is where you have got to, which means that "Sync to latest page read" won't work either. (But you could try it.)

In which case, the only way is to go back to the beginning and page forward until you get to where you were. Painful.

Do you have the Kindle app on other devices too? If so, you may have synced to the last page by mistake.

Aha! I just found this

Once you have got to where you want to be, you can reset it, apparently.
