I get a lot of email from readers saying "Books 1-3, 5, and 6 of your six-book Merchant Princes series are available as ebooks, but book #4 is missing. What gives?"
I am happy to announce that The Merchants War has been available on Kindle and, I am told, via B&N and iBooks, since November 19th.
(I'd be even happier if someone from my publishers had, like, told me, but the next time that happens will be the first time, so, well, better late than never.)
This means that if you're in the USA you can read the whole Merchant Princes series in ebook form. (Note that book #6, "The Trade of Queens", costs more than the earlier volumes because it's still in hardcover; it should get cheaper sometime next March, when the mass market paperback edition is released. Folks in other territories may be out of luck unless they can bamboozle one of the US vendors into supplying an ebook out of area. Yes, this sucks. Yes, when there's a fix I'll announce it here.)
