Having read Book 1 – A very unusual pursuit but being somewhat ambivalent about it (6 months on), I decided to re-acquaint myself with Jem, Birdie and Alfred Bunce as they seek to clear London of child eating monsters (bogles). A mix of fantasy, mystery and action – A very peculiar plague, seemed to provide more excitement, interest and less predictability than the first story with the reason for the plague of child eating monsters being somewhat unexpected. I also found myself wondering about what lies beneath the streets of London and thinking about so many of the other London mysteries I have read/watched. It is more suited to a Year 6-7 audience than older students (given that the main character is 11). I look forward to the next instalment.
