I love 101 Things I Learned at Architecture School.
It's a very light, approachable book, dealing with surprisingly universal principles. Also it has very nice pictures.
Most of it also applies to game dev, and to the design of experiences.
I improved my doodling skills from that book, but I'm not sure I learned anything generalizable.
