Pottermore just Tweeted its third message -- and first in six days -- and guess what?

It's a tease.

Only 17 hours, 17 minutes and 17 seconds until all is revealed, Pottermore Tweeted 9 minutes ago.

For live blog coverage of the announcement at 7 a.m. Eastern tomorrow morning, see ibtimes.com/books.

One more note: the website in question says that Harry Potter and Pottermore Publishing Rights (emphasis ours) are the copyrights of J.K. Rowling.
