When hostile ogres, goblins, and other faery beings start turning up at school, Taylor Smart is compelled to investigate. Why has somebody painted a target on her back this time? And why are they trying to drive a wedge between her and her friends in the Wonder? Answers aren't always easy to come by, especially when Taylor is thrown through a portal to a part of the Wonder that's infested with monsters, the worst of which walk on two feet. The River of Night has a way of testing the heroes who travel it. This is doubly true when someone behind the scenes is pulling strings for their own hidden purposes. One thing is sure: Taylor and her friends have once more been drawn into a deadly game of supernatural politics and intrigue. And the Fair Folk don't play fair.
