The main romance from the 2003 version of WoK has been pushed off to a later volume. Halfway through the book there isn't any romance yet and I don't expect any in this installment. I think Brandon is focusing on establishing who the characters are in their own right before moving on to the complication of romances. (I'm doubting Romantic Times would look as highly on this book as they did on Elantris and Warbreaker.)
Well, I somewhat take that back. In the first half there is a romantic relationship of sorts that is hinted at, but its nature is a big mystery that's not yet revealed. There are lots of mysteries for which putting the pieces together will take quite a while.
No wait, darn, there was definite flirting going on in a very recent chapter. Sorry; it's been too long since Brandon left on tour so there hasn't been a new chapter covered in writing group for a while. So there very well could be a lot more romantic content in the second half of the book.
Sorry! I'm not doing this quite right today.
