Douglas Hill, The Guardian: Chris Westwood writes a scary book about scary books in Calling All Monsters. Young Joanne finds that the horror creations of her favourite writer are crashing terrifyingly into her real life. And when she and the writer join forces to oppose them, she learns, like Dr Frankenstein, that it is deadly difficult to unmake your own monsters. You will never read another horror story again.
