The Regicide Report, the last novel in the main Laundry Files series, is coming out on January 27th in the US (from Tor.com Publishing) and the UK (from Orbit).
If you want to order signed hardcovers, contact Transreal Fiction in Edinburgh. (I believe Mike is currently willing to send books to the USA, but don't take my word for it: check first, and blame Donald Trump if there are customs/tariff obstacles.)
Audiobooks: there will be audio editions. The Audible one is showing a January 27th release date on Amazon.com; Hachette Digital will be issuing one in the UK but it's not showing up on Amazon.co.uk yet. (For contractual reasons they're recorded and produced by different companies.)
Ebooks and DRM: The ebook will be available the same day as the hardcover. Tor.com does not put DRM on their ebooks, but it's anybody's guess whether a given ebook store will add it. (Amazon have been particularly asshole-ish in recent years but are promising DRM-free downloads of purchases will be available from late January.) Orbit is part of Hachette, who are particularly obstreperous about requiring DRM on everything electronic, so you're out of luck if you buy the Orbit edition. (I could tell you how to unlock the DRM on purchases from the UK Kobo store, but then my publisher would be contractually obliged to assassinate me. Let's just say, it can be done.)
What next?
The Regicide Report is the last Bob/Mo/Laundry novel. It's set circa March-May 2015 in the time line; the New Management books are set circa November 2015 through May 2017, so this one slots in before Dead Lies Dreaming.
There may be a Laundry Files short story collection, and/or/maybe including a final New Management novella (it's half-written, but on "hold" since mid-2024), at some point in the future. But not this year or next. (I'm taking time off to get back in touch with space opera.)
None of the above precludes further Laundry Files novels getting written, but it's up to the publishers and market forces. If it does happen, I expect they'll be set in the 2020s in the internal chronology, by which time the Laundry itself is no more (it's been superseded by DEAT), and we may have new protagonists and a very new story line.
No, but really what's next?
I don't know for sure, but I'm currently working on the final draft of Starter Pack, my Stainless Steel Rat homage, and planning yet another rewrite of Ghost Engine, this time throwing away my current protagonists and replacing them with the ones from Starter Pack (who need another heist caper). Do not expect publication before 2027, though! I'm also awaiting eye surgery again, which slows everything down.
