Over the summer, producer Mark Amery's teenagers devoured the first two great books in a new series for young adults - and their parents - Children of the Furnace. They're by a Nelson author Brin Murray and set in a future inspired by the threats of climate change. Whether its The Hunger Games or Mortal Engines dark, almost post-apocalyptic futures in which teens save us from terrible endings have become increasingly popular - Children of the Furnace is a fine local addition. Mark's eldest Ali reads from the second book Crosstrees, which is due out February 21, and then Solly kicks off the conversation with Brin.
