(get book :authors) is saying "return the value of the ":authors" key in the "book" map. You provided {:title... :authors [octavia]} as the "book" map, the value of "authors" being a vector with a single element. That single element being "{:name "Octavia E. Butler"
:birth-year 1947 :death-year 2006}" In other words, it is all working correctly. Did you mean (old-book->new-book {:title "Wild Seed", :authors (:name octavia)}) ?
