Jeff Murray's new novel offers life after the Big Melt

It's 2048 and the dire predictions about climate change made decades earlier have come true. In his novel Melt, Auckland writer Jeff Murray imagines New Zealand's response to a wave of migrants. Would we still welcome ones from Pacific Islands when migrants from wealthy countries are a better strategic bet? Jeff tells Lynn Freeman that Antarctica may also become a potential new home after substantial ice melt. Melt is out on the Mary Egan Publishing label.
