There's several good Clojure books. I'd start with Rich Hickey's video "Simple made Easy":

The "Joy of Clojure" is the best book on understanding the mid and high level constructs and design of Clojure (and FP). It's not a beginner book though - for that the books from the Pragmatic Programmers or Oreilly are excellent.
