I have a book coming out this month; "The Trade of Queens", the sixth novel in the Merchant Princes series, is shipping (the official publication date is the 16th, but it should be showing up in bookstores in the USA from Monday onwards). And the last, for the time being — if you've been holding off starting on the series because you wanted to know there was an ending in sight, this is it. Series climax: finale: fat lady sings.
(You can find links to buy my books — including all the Merchant Princes titles — here.)
While this is the last of the current cycle, I'm not ruling out writing more books in that universe — but I'm taking a couple of years of time out first, and if and when go back to there, it'll be with a new story and mostly new characters.
I'm still slightly gobsmacked that I actually managed to write (and more importantly finish) this thing; a multi-volume novel about 30,000 words longer than "War and Peace", with a political subtext about economic development and a marked lack of good guys. One of these days I'm going to bolt my thoughts about writing larger-than-novel-length fiction together. But not right now ...
