A door in the OXEN universe has now closed

The seventh volume in the series, OXEN Interregnum, ties up loose ends from the first three books regarding the showdown with Danehof.

When will the Oxen series end? The Oxen series isn't ending anytime soon, is it? Oxen must never disappear, right?

Fortunately, there are many questions surrounding my protagonist and the series that bears his name — often voiced with a hint of concern. As an author, I am incredibly privileged to see such great interest in my hero, war veteran Niels Oxen — and his well-being. Sometimes I have to pinch myself at the truly immense level of reader engagement shown.

But... It is also abundantly clear that we are approaching the end. I never declared that the OXEN series would consist of a specific number of volumes... It will be finished when it is finished. Honestly, even I don't know when that will happen. Perhaps in two or three more volumes?
I have just one overriding thought regarding the conclusion: better to end too soon than too late...

With Interregnum, the seventh volume in the series, I am closing a door in the Oxen universe that has stood open for years: the final reckoning with the secret power elite, Danehof. In volume 3, De frosne Flammer (The Frozen Flames), we do get a conclusion of sorts — but we also learn that the organization's two successors are meeting at Amager Strandpark. A meeting that PET chief Axel Mossman eavesdrops on and records.

Since then, I have pushed the thought of Danehof somewhat into the background. But perhaps — as a small step toward concluding the long saga of Niels Oxen, Margrethe Franck, Axel Mossman, and the others — I felt it was time to close that door. Or, to put it another way: time to tie up the loose ends from back then.

And that is precisely what Interregnum is about: the final showdown with the Danehof.
I think it has turned into a challenging, complex story — Oxen books really ought to be complex — but perhaps more so than ever this time around. It has also become my longest Oxen story. The previous record was held by volume 4, Lupus, at 521 pages; Interregnum runs to a full 567 pages.

And there was no way it could have been any shorter, given that the door had to be closed with a real bang...
