A Memory Called Empire (2019)

An ambassador arrives to discover that her predecessor is dead, leaving inherited knowledge that may not answer the questions most urgently facing her. Martine makes language, etiquette and political allegiance part of the evidence, while a memory-preserving technology changes what continuity between investigators might mean. Choose it for a diplomatic murder mystery inside a seductive empire, with careful attention to names and conversation. A Desolation Called Peace continues the wider story.
