Ummm.. not exactly. Those seven books had been in the library for years, but the delay problem was only weeks old, and started suddenly, that is, one day everything was fine, the next morning the 55 second delay.

The only commonality I can find is that each of those seven books had been modified after being added to the library -- converted from .epub or .mobi into .rtf format so I could edit the books, then the edited file converted back into .mobi for the Kindle. But there are dozens, no, more likely hundreds of other books in the library that have gone through that process.
