Set in present-day New Zealand, in a picturesque seaside town, the people of the local community are suddenly and inexplicably overcome by a temporary madness that kills almost all of them. The Survivors try to piece together what has happened to the community and the clues lead them to an ancient Maori settlement.
I absolutely loved the start of this book, it was so simple but creepy. Policewoman Therese drives into town and discovers its inhabitants in a crazed, Zombie-like state, fluctuating between violent and comedic. It stood out as being a suspense story rather than horror, although some moments did have a gore factor.
