The Little Schemer series is a good introduction to Lisp/Scheme parenthesis-style recursive programming. https://mitpress.mit.edu/books/little-schemer-fourth-edition https://mitpress.mit.edu/books/little-schemer-fourth-edition https://mitpress.mit.edu/books/seasoned-schemer-second-edition https://mitpress.mit.edu/books/seasoned-schemer-second-editi... https://mitpress.mit.edu/books/reasoned-schemer-second-edition https://mitpress.mit.edu/books/reasoned-schemer-second-editi...
