But now a new threat has boarded, one that troubles even the Modhri.
 
While the Quadrail is en route to the farthest edge of the galaxy, a murder by poison occursthen another and anotherdark happenings that are not only disturbing but also technically impossible. The system Compton and Bayta have been charged with protecting is in grave danger of derailment, and unless they can get to the deep roots of a sinister conspiracy, chaos will come to the ordered universe.
