These are the first three stories of the Tollins. Yes, they do have wings, but no, they aren't fairies. Tollins are a lot less fragile than fairies. In fact, the word fragile can't really be used to describe them at all. They are about as fragile as a house brick. In "How to Blow Up Tollins" a fireworks factory comes to the village of Chorleywood and the Tollins find themselves being used as industrial supplies. Being blasted into the night sky or spun round on a Catherine wheel is nowhere near a much fun as it sounds. It's up to one young Tollin to save his people from becoming an ingredient. In "Sparkler and the Purple Death" our hero looks execution in the face. Luckily, the executioner's mask in backwards. Finally, in "Windbags and Dark Tollins" Tollin society faces a threat from the Dorset countryside, which, again, is much more frightening and nail-bitingly dramatic than it actually sounds.
