When we told our best friends, Raúl and Sonia, that a strange green meteorite had given us telepathic powers, they were amazed. After they’d got over the shock, what do you think was the first thing they thought of? That we needed to set up a headquarters! Meanwhile, Twin City was hit by a wave of disappearing dogs. What did these two things have in common? Well, quite a lot as it happens… But why don't you open the book and find out for yourself?” The collection has been downloaded over 500,000 times and received over 4,000 reviews with a score of 4.5 out of 5.
