What can I say without spoiling the plot for my beloved spouse, who hasn't read the previous book in the series, Issola. Auuuuggghhh! Give me back my husband, you foul MMORPGs! He isn't reading enough books anymore! And Issola is in a box somewhere, waiting for the big move! Double aaaaaaauuuuuuggggghhhhh!
I'm hoping the next book in the series will be about Vlad's adventures in the East--he keeps dropping hints about them--but it probably won't come out until the same weekend as the last Harry Potter book or something.
