So you've assigned the var "octavia" to the data structure:
{:death-year 2006, :name "Octavia E. Butler", :birth-year 1947}
(def wild-seed {:title "Wild Seed", :authors [octavia]})

Here you've assigned the var "wild-seed" to:
{:title "Wild Seed", :authors [octavia]}
Which is the same as:
{:title "Wild Seed", :authors [{:death-year 2006, :name "Octavia E.
Butler", :birth-year 1947}]}
So I thought when I do this :

Okay, so work through your code. You start with:
(old-book->new-book {:title "Wild Seed", :authors [octavia]})
Resolving this gets:
(get {:title "Wild Seed", :authors [octavia]} :authors)
Resolving this gets:
[octavia]
Which resolves to:
[{:death-year 2006, :name "Octavia E. Butler", :birth-year 1947}]
I'm not sure why you'd expect anything else. Did you not expect "octavia"
to resolve?
