Turns out it was released by Queen-Kitty in Olympia, Washington, USA, in June 2002. S/he released three books that month, with those being his/her only releases thus far. None of the three had been heard from since their respective releases, until yesterday's journal entry. The length of time between release and catch - 6 years, 9 months, 2 days - is an unofficial new BookCrossing record. "Unofficial" because it's impossible to know what each book's length of time is without going through each of them individually. Of the known lengthy release-to-catches, this one is the longest. Here's yesterday's journal entry:
Can you believe I have been sitting on this book for years. Ah, what bad kharma. I'm going to read and release this month, returning it to the Great River of Chance.
