Clojure Applied is an excellent book so far. I've been using Clojure for a long time, and it's still been very helpful in updating idioms for modeling domains, composing applications, etc.
I'd say it's required reading for working Clojure programmers, of any experience level. We really needed a "how to build applications in Clojure" to complement all the "how to do stuff in Clojure" books that are already out.
