It’s a chilly Auckland winter, but for Hana Westerman and her family, it is a time of excitement. Matariki is approaching – the small cluster of stars also known as the Seven Sisters is a sacred constellation in Māori culture, heralding a time of new beginnings. Hana’s daughter Addison is getting engaged and Hana’s new role within her community is going well. For once, life is good, peaceful.

But this Matariki brings unwelcome change. When Hana’s ex-husband Jaye, a high-flying Detective Inspector, is shot in what looks like a random hold-up, Hana offers her help to the senior police officer spearheading the investigation, DI Elisa Grey. With access to police intelligence, Hana makes a breakthrough that leads to a potential suspect with links to a Chinese organised-crime syndicate. But then Addison receives a phone call telling her that the police have the wrong man.

Was Jaye really just in the wrong place at the wrong time? Or is his shooting related to something else – an old undercover case deep in his past?
