Thanks for this stuff, folks - please keep it coming!
As RiggerBob points out, a "good merge" flesh form has very few problems hiding their aura.
The mom's a smuggler, so I could have her linked to the Desolation Angels - given that they were active in Chicago in the 2050s, and are active in Seattle in the 2070s, it fits nicely. They're known as bug hunters, amongst other things, and there are rumours that they're all mantis spirits*, so it works whether she's invested or still human. I think I'll go with invested, though.
Using the file as a "hit list" of her research was something I'd considered, so it's likely a direction I'll go in. Tying in the bug conspiracy stuff from Conspiracy Theories should put me onto a bit of a winner too.
This is what I've got as a first draft:
Anna “The Wildflower” Hanniver fell in with the Desolation Angels back in Chicago, where she joined up with them for protection and was invested as a Scout. Since then, she has travelled the world as a smuggler. As part of the UCAS Government’s efforts against bug spirits, she has been recruited as a CIA agent (the CIA know that she’s a bug) following the trail of the bug spirits that escaped from Ares Complexes 68G (Algonkian-Manitou Council), 93E (Shaanxi) and 211B (Indian Union). In particular, she has a brief to investigate the potential mega-hives in Cairo, El Paso, Kuala Lumpur, Moscow, Neo-Tokyo, New Orleans, Rome and Tucson.
As part of her investigations in Neo-Tokyo, she discovered that several higher-ups of the Watada-rengo, including Kumicho Yamajima, wakagashira-hosa of the Mita-gumi. Yamajima set an ambush for her, causing her to flee for her life, sending a copy of her research to her son in the hope of preventing him from coming to harm. She has gone to ground in Manhattan, trying to investigate the possible hives there.
*: certainly, the ones we encounter in Burning Bright are!
