This is excellent news:
For those unaware, Rivers of War is Flint’s alternate history of the American frontier. He picked an interesting divergence point (Sam Houston only getting slightly wounded at a particular battle), and then things went interestingly weird from there. So interestingly weird I had to delete the details, because spoilers.
It’s one of my favorite series, and I’ve been waiting years for Flint to get past two books in it. Something to look forward to in 2023!
