What can a banal request from a sick colleague to visit her elderly relative lead to? Waste of time? Returning home a couple of hours later? No matter how it is! For me, this turned into an experience of fear and a completely undesirable acquaintance with a world whose laws are fundamentally different from the usual. It is inhabited by a mass of strange and mostly dangerous creatures, and it turns out that I am part of it, although I never suspected it. And, apparently, after this unpleasant discovery there is no turning back for me. You will have to learn to survive in this world of non-humans, to look for allies or at least those whose plans do not include killing you or using you. Book one.
