(There is apparently a sequel, but I've been strongly warned not to read it and I do not intend to do so; this book works tremendously well as a standalone!)

Because I am extremely sleep-deprived and read in blocks, for a moment I thought this sentence was referring to Entangled Life (which I have read and very much enjoyed, as a person who has a significant affinity for fungi and none whatsoever for LSD) and I was confused.
