I would love to see a sequel.  Remember that at one time there were several more books planned for the series.  Then again, none of the Dread Empire Novels really had a strong "this is it" ending.  Most weren't cliffhangers, but they weren't like the ending of the Tower of Fear (which had one epilogue for the characters and another for the world).  Maybe he was aiming for one of those types of endings here.
