The Driver’s Seat, Spark’s own favorite among her many novels, was hailed by the New Yorker as “her spiny and treacherous masterpiece.”
Driven mad by an office job, Lise flies south on holiday — in search of passionate adventure and sex. In this metaphysical shocker, infinity and eternity attend Lise’s last terrible day in the unnamed southern city that is her final destination.
