Note on Jao Empire series
Posted on July 19, 2012 by Eric Flint
"A number of people have asked me if I’ll be continuing the Jao Empire series I’ve been doing with Kathy Wentworth, now that Kathy has passed away. (She died in April from complications following cancer surgery.) The first two books in that series were THE COURSE OF EMPIRE and THE CRUCIBLE OF EMPIRE. Kathy and I had started a third book in the series, with the working title of THE SPAN OF EMPIRE. 
… I’ve been discussing the situation both with Kathy’s husband, who controls her estate, as well as Baen Books. I think we’ll be able to work something out to everyone’s satisfaction so that work can resume on THE SPAN OF EMPIRE." - Author Eric Flint's Home Page  http://www.ericflint.net/index.php/2012/07/19/news-7-19-12-jao-empire-series-2/
