Sagan manipulates her chain of command to promote John to an advisory role (as a lieutenant) to gather information from the Consu during a ritualistic meeting to obtain information. Perry discovers that the Rraey had received the skip-drive detection tachyon technology from the Consu, which was used to set up the ambush at Coral. Perry also manipulates his chain of command to have the last two of his friends from the "Old Farts" transferred out of combat duty to military research. Sagan and Perry then participate in a Special Forces operation in an attempt to capture or destroy the borrowed Consu technology in advance of a major attack to recapture Coral from the Rraey. Perry is instrumental in the successful outcome of the battle by capturing the technical manual for the Consu detection system (which was destroyed in the fighting), and saving Sagan's life after she is severely wounded. However, he never sees her again after delivering her to a shuttle which returns her to the secretive Ghost Brigades.
