File this one under better late that never: at last, both print and e-copies of Credible Threats, Sam Adams book one, are available for wide release. Basically, that means you can order it from far more venues than just Amazon, which was the only place it was sold when it was first released. Here’s a universal buy link: https://books2read.com/crediblethreats
As for Rising Shadows, I’m a little more efficient this time: it will be released wide as soon as it comes out, on April 16, 2024. It’s currently available for preorders from several online booksellers: https://books2read.com/risingshadows. If you don’t see your preferred venue there, check back later; it will be updated as we get closer to the release date.
