Start with The Warrior’s Apprentice
- This book starts the main series of Miles Vorkosigan. Everything you need to know is either explained or assumed.
The Vor Game - There is a book (novella), which fits between the Warrior’s Apprentice and The Vor Game. I have this novella included in another book which is actually a set of three novellas given as a report to Miles’ C.O.
Cetaganda - This book follows The Vor Game directly in the series.
Brothers in Arms - If you’ve made it this far in the series you’re probably hooked.
The Borders of Infinity - This is the collection of three novellas mentioned earlier, these novellas occurred at different points in the timeline of the series, but none of them occur any time further on in the series, so no spoilers. I consider these novellas to be integral to the whole series.
Mirror Dance - The timeline of the series picks back up here.
Memory - Continuation of the series, this book is something of an evolution for Miles.
Komarr - Continuation of the series.
A Civil Campaign - Continuation of the series.
Winterfair Gifts - Novella
Diplomatic Immunity - Continuation of the series.
Captain Vorpatril’s Alliance - This book does not actually follow Miles as the main character, but instead follows his cousin Ivan. Don’t miss this one; it’s really amusing.
Cryoburn - The last book in the main series. If you've liked it all so far the other books give context and are generally enjoyable.
Falling Free/Shards of Honor/Barrayar - These three books are something of prequels to the main series. I suggest that if you read these at all, you read them after you read the main series. They are interesting but more of a footnote. Also if you do read these, note that they were written by the author after the main series.
Ethan of Athos - This book falls in-between Cetaganda and Brothers in Arms in the timeline. This book does not feature Miles, but does feature Elli Quinn. This is another book that should only be read after the main series.
