Except the queen

From award winning authors Jane Yolen and Midori Snyder comes a tale of two worlds-and one destiny... Sisters Serena and Meteora were once proud members of the high court of the Fairy Queen- until they played a prank that angered her highness. Separated and banished to the mortal realm of Earth, they must find a way to survive in a strange world in which they have no power. But there is more to their new home than they first suspect... A sympathetic Meteora bonds with a troubled young girl with an ornate tattoo on her neck. Meteora recognizes it as a magic symbol that will surely bring danger down on them all. Serena, meanwhile, takes in a tortured homeless boy whose mind is plagued by dark visions. The signs point to a rising power that threatens to tear asunder both fairy and human worlds. And the sisters realize that perhaps the queen cast them from their homes not out of anger or spite- but because they were the only ones who could do what must be done... -Goodreads
