We've also got another DS9 focused novel coming out at the end of the year, in the form of the first book in the new post-Typhon Pact miniseries, The Fall: Revelations and Dust.
And if you want more DS9 then keep buying and voicing your support for it! The Fall will have DS9 stories as well as threads in each of the books so lets make sure Pocket knows we support more DS9 stories with our pocketbooks!
Note to CBS/Pocket Books: I bought Allegiance in Exile
just for the Ascendants.
