Far too much “Ra! Ra! Clojure is the bestest!” for my taste. The order in which concepts are introduced is not well suited to understanding the examples provided. The arrow macro, for example, is used repeatedly early in the book; well before any meaningful explanation is given for how it works or what it is doing. I found these unexplained intricacies distracted from understanding the examples as they were given. A disappointing read, overall. This is an excellent introduction to Clojure, whether you've Lisped before or not. It doesn't go into great depth, but it's valuable both as an introduction and as a reference for the new Clojure developer. I personally like programming books with a language + standard library reference included (e.g., Programming Ruby), but the Clojure online docs are comprehensive enough that it's not entirely necessary here. Like just about every PragProg book I've read, this is an excellent survey of the subject matter.
