Clojure for the Brave and True is, in my opinion, more substantial than _why's Poignant Guide. It moves faster, guides you through some real (if small) projects, and the whimsical tone is really just some flavoring rather than the whole focus of the book. _why's guide really seems only to be incidentally about programming in Ruby because it's focus is being some kind of crazy postmodern deconstruction of programming tutorials, while Clojure for the Brave and True is the inverse, if that makes sense. I think it's a good introduction, and as someone who's programmed in a lot of languages over the years it was accessible without being too dumbed-down. The style certainly isn't to everyone's taste, of course.
