How to buy the books

The trilogy is complete and all books are in their final updates. I've officially quit Darwin, but the books are and will always be available (yep. October 2023 and they're still available) for purchase, and (I hope) will be (relatively) future proof. I actually feel like it would be great if I could update them (specifically, I/7, DYLD (chained fixups) and II/12, kernel zones, had some noteworthy changes), but I've been gagged. Sorry. But really most everything else is still just as relevant.
