Emma Owens is a seemingly ordinary seventeen-year-old girl who covertly possesses the power to do anything she desires, without limitation, in a world filled with both infinite beauty and interminable danger, that exists only while she sleeps. Emma is a dreamwalker.
She inherited the dreamwalking trait from her father and inexplicably shares it with her best friend, Zoë. There are rules to dreamwalking that Emma and Zoë live their lives by. The most important of which is not to interact with unknown people who can see them while they dreamwalk, or risk becoming lost in a world of unrelenting darkness. Emma and Zoë have always followed the rules without question, but their conformity is tested when Emma learns that she is the only one capable of rescuing a young girl who has become profoundly lost on a dreamwalk. When Emma launches a crusade to travel deep into the world of dreamwalking, gambling her own life to save the girl, Zoë agrees to stand by her side, unknowingly opening the door to her own astounding hidden faculties and uncovering a three hundred year old family secret in the process. Emma's world is turned even further upside down when Charlie, the boy who shattered her heart into a thousand jagged pieces, mysteriously returns with information that sends her head... and heart, spinning.
