Every ask yourself what would happen if the Modhri and Frank Compton found a threat so menacing they'd actually consider working together? Ask no more. Zahn handles it brilliantly, particularly with his cast stuck from early on aboard a Quadrail train the entire story. Great pacing, action, thriller and mystery elements combine with the usual humor and character growth. A worthy entry in the great space opera series. And it ends with such a fantastic cliffhanger that will have you foaming at the mouth for the next book which comes out soon. Seriously, I am on the edge of my seat to see what happens next.
