This intriguing story features a boy who is compelled to find coping mechanisms for real and metaphorical darkness. What is exceptional in this text is the way in which the real and the imaginary are seamlessly merged so that its sober themes (including domestic abuse) can be processed through fairytale filters of cottages in the woods, jars of light and mystery treasure hunts. This brave and thought-provoking book brilliantly captures the feeling of finding oneself caught on thresholds that will seem familiar to readers in upper KS2, such as childhood versus adolescence, attachment versus separation and reality versus imagination.
