Book 2: Wasteland is due out in December.
When in December I'm not sure, but as the hours and days have been ticking past this week, my eyes have been increasingly drawn to my calender (and its rather fetching print of a cafe on the Seine), and I grow increasingly aware that December approaches (and how nice it would be to be in Paris right now) and the book is not quite ready.
I thought it was finished last weekend, but as I've been looking at my notes for book 4, set 10 years after the evacuation, I felt that something was... just not... it wasn't...well... It's hard to put my finger on it, but something didn't quite fit. I can't be more specific because it will ruin the plot of Book 2, 3 and 4 (and half a dozen short stories in between.) So you'll just have to take my word for it, that any delay is for the good of the narrative.
It will be out before Christmas, probably around the 10th December, unless I succumb and catch a train to France instead... the Eurostar isn't far from here, after all, not really much more than a short bus trip...
