I've started reading Lois McMaster Bujold's Miles Vorkosigan series, but apparently the publication order and chronological order are different - so I'll list the reading order of the main novels below:
1. Shards of Honor (1986)
2. Barrayar (1991)
3. The Warrior's Apprentice (1986)
4. The Vor Game (1990)
5. Cetaganda (1995)
6. Brothers in Arms (1989)
7. Mirror Dance (1994)
8. Memory (1996)
9. Komarr (1998)
10. A Civil Campaign (1999)
11. Diplomatic Immunity (1999)
12. Captain Vorpatril's Alliance (2012)
13. Cryoburn (2010)
14. Gentleman Jole and the Red Queen (2016)
There is also the novel Falling Free, which appears to be set around 200 years before Shards of Honor and doesn't include the characters or settings, so I've left that out - as well as Ethan of Andros, which is a side story involving a couple of minor characters from the series and set after Cetaganda.
I've specifically not included the omnibus editions, which collect together some of the earlier novels into single volumes, as these don't normally appear available in the UK.
There also seems to be a number of short stories/novellas that are set in the same universe, but don't necessarily include the characters directly or involve the main plot developments and can therefore be overlooked without apparently missing anything significant, which I've numbered below according to the novels:
3.1 The Mountains of Mourning (1989)
3.2 Weatherman (1990)
5.1 Labyrinth (1989)
5.2 The Borders of Infinity (1987)
10.1 Winterfair Gifts (2002)
13.1 Flowers of Vashnoi (2018)
If any of the above needs correcting, let me know below.
