Great book, interlaced with stories, teaches you cool stuff that you didn't know you wanted to know about all sorts of structures: compression (masonry buildings), tension (boiler shells, bows), how stress and strain basically works, how joints fail, beams, torsion forces, the ways of buckling in compression. It sounds boring listed but it's not boring in the book. I really like the abundance of diagrams and plates.

Would definitely recommend.
