I used to love Peter Dickinson when I was you get, but this just didn't do it for me. There's nothing particularly wrong that I can put my finger on, but I just didn't enjoy it and skimmed through the second half. It's a cool idea, with lots of potential for intrigue, mystery and even a little kiddy-horror, but the voice of Keith, the narrator, just strips all of the passion out of it. I also though that hearing from a first person narrator, but NOT one of the girls whom the mystery is about sapped much of the drama and suspense. Although I'll keep it on my class bookshelf, it won't be one of my go-to recommendations, he has other, far more engaging, stories.
