A good teacher can change lives... Every evening, Allison watches her husband's new house, desperate to find some answers. Every morning, she puts on a brave face to teach kindergarten. She's a good teacher, everyone says so - this stalking is just a tiny crack in her usual self-control. A late enrolment into her class brings little Gracie - sick and grieving. Allison takes the girl and her father, Luke, under her wing. She smothers Gracie with the love she can't give her own son. As others question her judgement and the police arrive at her door, Allison starts to wonder if she can trust herself. When Gracie has a chance to go to America for treatment, Allison leads the school in a fundraising drive. But has she crossed a line? How far will the good teacher go to save a life? And whose life will that be? An intriguing tale of our times about kindness and betrayal, and the danger of good deeds.
