Meredith is having weird visions. The Island of Kaitangata is waking up. For the first time in years there is an earthquake — the Kaitangata Twitch. Meredith sees a young girl on the Island and discovers she went missing in mysterious circumstances — 50 years ago!

Meredith realizes that Lee Kaa believes there is a connection between the earthquakes and her visions. Her grandparents visit and Nana drops a bombshell — she knew Shelly Gentry and believes Lee Kaa murdered her.

Tensions rise in the house as Dad accepts Cardwell's offer to design an eco-friendly development. Meredith has her most frightening vision yet — while in real life she paddles out to Kaitangata in her sleep. And she is being followed...

Meredith turns 13 but it is not a happy occasion. With her family in turmoil, Meredith realises that the island is about to bite back — but she finds herself alone in the battle to calm its wrath.
