"Give me the Crystal Key!" Will Dreycott is the Dream Rider, the agoraphobic teenage superhero who can walk in our dreams but never in the streets of his city. Case is his girlfriend, a survivor of those streets who hears voices that warn her of danger. Fader is her brother, who is very good at disappearing. Together, they defeated a body swapper and a witch to save the world (The Hollow Boys). Now, Case battles guilt over living sheltered in Will's tower home while her street friends still struggle. Blaming his affliction for Case's sadness, Will searches for a way to live a normal life with the girl he loves--a way to go outside. But his efforts draw the attention of dark forces. Sinister figures hunt Will in Dream. Intruders scour the vast warehouse of antiquities "acquired" by Will's missing parents. And a masked swordswoman attacks Will, demanding "the Crystal Key" before disappearing into thin air. Are they all searching for the same thing? Something from Will's parents' shady past? For the swordswoman leaves behind a flowery scent, Will's only memory from the lost expedition eight years ago that gave him powers in Dream but cost him his parents and his freedom. A trail of dark secrets leads Will, Case, and Fader to a mysterious world. Trapped between warring cults willing to kill for the Crystal Key, the three friends must master strange new powers that grow stronger and wilder the closer they draw to the truth. This time it's not just the fate of the world at stake...but the multiverse.
