So I finished my reading of Quick Clojure and can report that it is well worth the read. The title is true to it's intention in that the book is short and you can get through it quickly. I'm not sure in not being a beginner how a new user of Clojure will respond but I'll lean to this being a good book to start with.
For more of an intermediate Clojure user there is still value to be found. I can point towards the Pattern Matching and Concurrency chapters as particularly worth reading.
