I am not an architect and now I don't need to be. I bought this book purely as a reference for my writing craft, and I am very glad I did so. This is the Gray's Anatomy of architecture, if you will, presented in an easy to digest visual manner. It takes some digging to find exactly what you want, because the book is organized so that taxonomic categories and theoretical ideas are interspersed in a way that doesn't always make sense, but, if it's architectural in any way, it's in there. An extremely useful resource when trying to figure out exactly what it is your heroine is dangling from beneath the tentacled monster shambling toward her over the roof.
