2008’s Emissaries from the Dead is the second story and first novel in Adam-Troy Castro’s Andrea Cort series.
When she was eight, Andrea Cort’s home community on Bocai descended into violent mass insanity. Cort succumbed to the madness but emerged one of the few survivors. Cort still thinks of herself as a Monster-with-a-capital‑M but her trauma makes her valuable to the Homo Sapiens Confederacy Diplomatic Corps. The Corps stands between Cort and the aliens who would like her tried for her past. If Cort is to stay within the Corps’ safe harbour, she must accept every crappy assignment they hand her.
Which is how Associate Legal Counsel for the Homo Sapiens Confederacy Diplomatic Corps Judge Advocate Andrea Cort finds herself headed to One One One, with strict orders to find a politically acceptable person to blame for a brutal murder, regardless of who the actual killer might be.
