Book excerpt: This overwhelmingly hot summer everything seems to be slowing down in the tiny Devon village where Alison lives, as if the sun is pouring hot glue over it. 'This idn't nothin',' says Alison's grandmother, recalling a drought when the earth swallowed lambs, and the summer after the war when people got electric shocks off each other. But Alison knows her grandmother's memory is lying: this is far worse. She feels that time has stopped just as she wants to enter the real world of adulthood. In fact, in the cruel heat of summer, time is creeping towards her, and closing in around the valley.
