Re-read: Authority, by Jeff Vandermeer. The second in the Southern Reach trilogy, and the direct sequel to his most famous novel, Annihilation. Vandermeer is the king of New Weird, and hailed often as a sci-fi/horror writer, but he is an underrated master of the Spy novel as well, and it shines through here. It also manages to take the unsettling nightmare of Annihilation and make it even more terrifying.
New Physical book: only slightly cheating here, but Ally by @makyo, creator of the Post-Self cycle and universe. Ergodic, deeply personal, an amazing example of unintentional plural literature (also ironic, considering recent developments) and prose so lilac it belongs at a festival in my hometown. Completely unrelated to the Post-Self Cycle, but absolutely set the stage for them. I haven't finished it yet, but that will not stop me from recommending it.
New non-physical book: @eatthepen's spectacular novel here on cohost: The First Step. A truly wild and mindbending story that walks a line between clinical hard sci-fi and beautifully expressed existential horror. I linked the first chapter, it is absolutely worth your time. And time, after all, is everything.
