Think your family is dysfunctional? Meet the Flynns.


For the three Flynn daughters, it’s been disastrous since their parents opened up their marriage. Abigail, the eldest, is dating an ex-soldier several years her senior nicknamed ‘War Crimes Wes’. Louise, the middle child, maintains a secret correspondence with an online terrorist. And the brilliant youngest, Harper, is being sent to a wilderness reform camp due to her insistence that someone – or something – is monitoring the town’s citizens.

Casting a shadow across their lives is Paul Alabaster, a nefarious local billionaire. Rumours of corruption circulate, but no one dares dig too deep. No one except Harper, whose obsession with Alabaster’s machinations sends the family hurtling into a criminal conspiracy – one that may just, finally, bring them closer together.
