Echo. Mirror World: New York. Parisian Empire.

Echo is a mirror world to Earth. We find our cities, our countries there, but there are differences: electricity does not exist, dragons have replaced airplanes, subway cars are located on the backs of strange centipedes... But the most surprising are the plushons. Those who hold the reins of this world in their fluffy paws... Student Furmill and Yuri, sitting in the adjacent seat on board a "Boeing-747" flying to New York, have moved to Echo and must learn to live in this place. This becomes much more complicated when Furmill discovers the spirit of her deceased aunt in her body...
