Not sure if this was such a good idea now

I just finished re-reading What a Dragon Should Know, loved it of course, but now I'm not so sure that was such a great idea since it just whetted my appetite for Eibhear and Izzy's story more. Does anyone have any updates about that? Is the book in the works? Because I'm prepared to beg G.A. Aiken and offer her a muffin basket if it would help speed things up a bit.
