As of 10/17, still no title or description on TLC's website or my cable guide. I'll keep checking and update when it shows up. I don't think that this is a good sign for the series that it's taking TLC so long to put up a title and that they've dropped the repeats and reruns.
Ah, the illegal fireworks faked for the Fourth perhaps?
Update: Official description is up.
The Duggars are lighting up the sky after the family purchases fireworks for the 4th of July. Then, Jim Bob takes some of the family to their first fencing lesson. And finally, the older girls start preparing for Michelle's birthday celebration.
