This is book 8 of the "Miles Vorkosigan" series.
This note contains spoilers for the book.
On his next mission after Mirror Dance, Miles has a seizure in combat armor while holding a plasma arc (I think it's built in). This turns out sub-optimally for Lieutenance Vorberg, the courier they're supposed to be rescuing. Also Quinn and others have a thing or two to say.
Then Miles leaves it out of his report. And of course Ilyan gets the information through other channels. And Miles is chashiered.
But that's just the setup for the real story.
Ilyan's memory chip is acting up; turns out eventually it's been hit by a tailored bio-thingy that Ser Galen and the Komarran terrorists came up with for precisely that purpose, which has been sitting on the shelves in the evidence room for years.
Miles gets assigned as temporary Imperial Auditor to investigate (both the actual problem, and also the treatment of Simon). Lois does put a discussion about how personal probity is one of the most important characteristics of an auditor right next to four of the existing auditors reading Miles' file, which tells about his falsifying the report to omit his seizures, and burning off Vorberg's legs. I'm not sure I'm buying it; there seems to me to be a problem there.
