They came together at Mountainview College, a down-at-the-heels secondary school on the seamy side of Dublin, to take a course in Italian. It was Latin teacher Aidan Dunne's last chance to revive a failing marriage and a dead-end career. But Aidan's dream was headed for disaster until the mysterious Signora appeared, transforming a shared passion for Italy into a life-altering adventure for them all ... bank clerk Bill and his dizzy fiancé Lizzie: a couple headed for trouble ... Kathy, a hardworking innocent propelled into adulthood in a shocking moment of truth ... Connie, the gorgeous rich lady with a scandal ready to explode ... glowering Lou, who joined the class as a cover for crime. And Signora, whose passionate past remained a secret as she changed all their lives forever.
