I have the following vector of structs:

(defstruct #^{:doc "Basic structure for book information."}
  book :title :authors :price)

(def #^{:doc "The top ten Amazon best sellers on 16 Mar 2010."}
  best-sellers
  [(struct book
           "The Big Short"
           ["Michael Lewis"]
           15.09)
   (struct book
           "The Help"
           ["Kathryn Stockett"]
           9.50)
   (struct book
           "Change Your Prain, Change Your Body"
           ["Daniel G. Amen M.D."]
           14.29)
   (struct book
           "Food Rules"
           ["Michael Pollan"]
           5.00)
   (struct book
           "Courage and Consequence"
           ["Karl Rove"]
           16.50)
   (struct book
           "A Patriot's History of the United States"
           ["Larry Schweikart","Michael Allen"]
           12.00)
   (struct book
           "The 48 Laws of Power"
           ["Robert Greene"]
           11.00)
   (struct book
           "The Five Thousand Year Leap"
           ["W. Cleon Skousen","James Michael Pratt","Carlos L Packard","Evan Frederickson"]
           10.97)
   (struct book
           "Chelsea Chelsea Bang Bang"
           ["Chelsea Handler"]
           14.03)
   (struct book
           "The Kind Diet"
           ["Alicia Silverstone","Neal D. Barnard M.D."]
           16.00)])

I would like to sum the prices of all the books in the vector.  What I have is the following:

(defn get-price
  "Same as print-book but handling multiple authors on a single book"
  [ {:keys [title authors price]} ]
   price)

Then I:

(reduce + (map get-price best-sellers))

Is there a way of doing this without mapping the "get-price" function over the vector? Or is there an idiomatic way of approaching this problem?
