When Jack, the driver, leaves Sophie at the blue house, she joins the other teenagers who wait there. Welcomed by Henry, the leader of the group, she is introduced to a world where they move unseen throughout the nameless city, riding on air. With the help of the operator, an ancient map and anything else they might need, they always manage to be at the right place at the right time. But someone is seeking to interfere with their work, watching and planning, and when something important is taken from the blue house, it is up to Sophie to get it back. As she struggles to retrieve the stolen article, she is reminded that her growing relationship with Michael, who is also waiting at the blue house, is against an unspoken rule that involves the one thing they can’t seem to control…their destiny
I have to say I really like this book. It has just enough conflict to keep the reader hooked without being overwhelming or getting beyond the plot of the story.
I didn't know what to expect when I started this trilogy, but all I can say now is that I am so very glad I read it. It makes you think while also telling you a story where you really love the characters. I recommend this to everyone
