I'm glad you asked that because I think Amazon is saying April, but although I am going full out at present, I don't think this is realistic. I'm doing my best, but I think we're probably talking third quarter. I have a lot of things competing for time at present, including a big flap in the day job and a PhD thesis. I also have a commission after this one for which I'm doing the fieldwork. If it's any consolation what I've got so far is looking pretty good (I would say that wouldn't I !!) and I have some interesting new material on Abu Klea, in particular, and a few new ideas about the evidence surrounding the battle.
But thanks for asking...I hate being behind time, but at least VWF members and their chums will know not to hold their breath. I've written 4 books in 5 years so far, and counting the forthcoming one 5 in 6 years. If I could do it any faster I would...but.....I can't!
