At Baytree Primary, it's the adults who are behaving like children... Lizzie, Megan and Sam became accidental friends over good coffee, banter and wrong-world jokes at school drop off. Lizzie is a part-time midwife with four kids and a secret past. Sam is an ex-chef and stay-at-home dad with an absent, high-flying corporate wife. Megan is an ex-model single mum with a thriving online business and no time for loneliness. None of them have much interest in their school community, but when tragedy deals Baytree Primary's reputation a potentially crippling blow, this unlikely trio have to step up. Forced out of their respective comfort zones, Lizzie, Megan and Sam learn more about each other, the school and themselves than they thought possible.
