Hene and the Burning Harbour

Hene is a Maori girl living in 1840s New Zealand. When her twin brother falls dangerously ill, her parents fear she will also catch the sickness, so they send her away from her home at the pa to the Paihia mission station. Life with the missionaries is difficult. Hene must wear an uncomfortable European dress and learn to sew, which she hates. Meanwhile, across the water in Russell, the world is in turmoil. Hone Heke has cut down the flagpole again and has attacked Korororeka. Hene sees smoke and fire from across the bay; the town is on fire and her best friend from the mission house, Rangi, is trapped there. Hene is the only one who can save her.
