Andrea y los masticadores

A world without electricity, a place where the trains are powered by monster's burps and the rooms are lit by the glare of giant glow-worms. This is the world of Andrea and the masticators, where children scratch monsters' backs to obtain energy. But suddenly, the delicate balance between humans and animals is threatened by some disturbing disappearances. Andrea, who is anything but a traditional heroine, sets off with her gang to solve the mystery. The investigation into the disappearances will ensure that their holidays are much more dangerous (and fun) than they could have imagined.
