Portals that can be travelled through with the help of a Luopan, a society of dreamers, and cities in the sky - when Chinese native Lai Fang meets the mysterious S., she doesn't know that this is the starting point of a journey into a world of Chinese magic. Having lost a big part of her memory due to a supposed accident, only one thing is on her mind: finding her Dad and reconnecting with her past. While S. wants to help her at first, he is not really what he seems - and Lai Fang has to escape from New York. She winds up in Beijing, the place where all her Dad's clues lead and where his past lies. Luckily, the Dreamer Society, who is responsible for the cities in the sky - cities made of dreams that house a part of the Chinese population due to the growing overpopulation - supports her in her quest. Or is Lai Fang just being fooled again? And will S. just give up without a fight?
