I very much like: "Sets for Mathematics", which I currently read and which finally clicks with me. I always found expositions of category theory tiring in that it bombarded me with trivialities and examples that were kind of obvious. Instead, "Sets for Mathematics" describes one particular and probably the most familiar and important category, the category of sets, and I very much like this fresh look at sets.
