BRIEFING: Nyx has been ordered to kill a rogue operative named Ripien, who has aligned himself with an organization called Pangaea. She is also to acquire whatever info she can regarding the organization. But there is more than one Pangaea, and none of them claim Ripien. A leak in Blacklight compels Nyx to regard everyone as inimical—and no one is who he or she claims to be, even her boss, Deven. Nyx has four days to complete her mission…if she lasts that long.
