After the party / Cassie Hamer.

Lisa Wheeldon has a lovely life. Wife to a gorgeous husband, Scott, and a devoted mother to two small daughters, the former accountant has everything she wants - except a third child. But the universe has a strange way of providing. On the surface, Ava's fifth birthday party seems the ideal opportunity for Lisa to meet her daughter's new kindergarten friends - all 32 of them! But from beginning to end, the day is a complete nightmare, capped off by the discovery of a little girl hiding in the Wheeldon's backyard. At first, Lisa reasons that Ellie's mum is running late. But when they open a gift from the mysterious little girl, it becomes clear her mother has no intention of returning at all... What sort of mother abandons her child? And why has she chosen the Wheeldons? Together, Lisa and her sister Jamie launch their own efforts to find the missing mum, a journey that will force Lisa to face her past, Jamie to confront her future and see both embroiled with angry exes, pragmatic fortune-tellers, Russian mobsters and a hyena pack of yummy mummies. A journey that will force Lisa to rethink all she knows about being a good mother.
