A collection of 21 short stories loosely divided into six different categories, ''To Hold the Bridge'' will probably divide opinion amongst readers. It’s undoubtedly a must-read book for fans of Garth Nix and these fans will, I suspect, quibble with my four star rating and challenge me to add another star. Those new to Garth’s writing might, in turn, think I’ve been over-generous given the mixed nature of the stories in the book.
