Hikaru Adachi has come to Andross Station to discover what happened to colleague and fellow Inquisitor Katya. Thane, a tracer, has arrived at the station seeking a bounty on Galen Horn, one of the Unity of Planets' most wanted men. They will find their paths cross as their interests intersect, and soon they are on a hunt that is more dangerous than they know, for Horn has enlisted some dangerous allies, including one from Thane's past. If Thane and Hikaru together can't bring Horn down, he will set in motion a plot that will see the entire station destroyed in an attack of massive proportions.
