Sue Rostoni announced today on the StarWars.com forums that author Paul S. Kemp (Crosscurrent) has been signed for a duology. Publication dates and format are not yet nailed down.
Kemp has two novels on the schedule for next year: The Old Republic: Deceived (March 22) and Crosscurrent sequel Riptide (July 19.)
UPDATE 9/28: Sue Rostoni says the duology will be hardcovers.
Good news, I think he did a good job with cross current and hopefully will get better the more he writes in the EU.
