"Cetaganda (Miles Vorkosigan Adventures)" by Lois McMaster Bujold
https://www.amazon.com/Cetaganda-Vorkosigan-Adventure-McMaster-Bujold/dp/0671877445/
Book number seven (in chronological order) of a sixteen book space opera
series. However, some people call this a military science fiction
series. There are several other books and short stories in the
Vorkosigan Universe. This series won the Hugo and Nebula awards for
best series in 2017. Also, several of the individual books in the
series have either won awards or been nominated for awards. I have read
this book several times as it is one of my favorite books. I reread the
well printed and well bound new MMPB published by Baen in 1996 that I
just rebought on Amazon. I have rebought the rest of the books in the
series in various formats, mostly MMPB.
Lord Miles Vorkosigan and Lord Ivan Vorpatril have traveled to the lead
world, Eta Ceta IV, of the Cetagandan empire to represent their planet
Barrayar at the Empresses funeral. Communications between the two
empires are still stressed due to the attempted invasion by Cetaganda
fifty years earlier which resulted in the deaths of five million
Barrayar citizens, mostly due to planetary bombardments using nuclear
weapons. As usual, Miles is in the middle of a conspiracy, this time at
the center of the Cetaganda Empires internal politics.
