Ayisha Synnestvedt, who adapted the play, describes herself as “a big Tarkington fan” who’d very much like to see a resurgence in Tarkington’s popularity–very much my own motivation for adapting Beasley’s Christmas Party a few years ago. She describes her adaptation of Seventeen as “very faithful to the book, with a few amputations for length and PCness that don’t take away from the spirit of it.”
