An OMW Universe Chronology
1. Old Man’s War (novel)
2. Questions for a Soldier (short story)
3. The Ghost Brigades (novel)
4. The Sagan Diary (novelette)
5. After the Coup (short story)
6. The Last Colony & Zoe’s Tale (novels)
The Last Colony and Zoe’s Tale take place simultaneously, which is why they’re listed on the same line.
(If you’re curious as to the order in which they were written: OMW, TGB, Q4S, TLC, TSD, ZT, AtC.)
I suspect that in the short term, if I write any additional short stories in the OMW universe, I’ll slot them in the same timeframe as “After the Coup,” i.e., before and during the events of the last two novels. I’ll do that partly because that’s a lot of time to explore (most of a decade, in fact), and partly because I have to have a nice long think about where the OMW universe goes after the events of TLC and ZT.
Also, a reminder to the folks who haven’t read “Questions for a Soldier” (which would in fact be most of you, since it was published as a chapbook, of which only 576 copies were printed) that the short story is being reprinted in the Subterranean Magazine #8, which will be the final printed version of the magazine (it’s mostly migrated online). So for you completists, that’s the way to go.
As for future OMW universe novels, I have to finish The High Castle and at least one other standalone novel (new universe, no relation to the OMW or TAD universes) first, and as noted earlier, no further OMW universe books are currently under contract. And anyway, four novels in the same universe in three and a half years is, you know, a lot. So for the next year or two at least, anything new in the OMW universe is likely to come in the form of short stories. Don’t worry, I’ll let you know where you can find them if and when they come out.
And that’s the whole OMW universe for you, so far.
