Cassandra Clemings has always seen a shadowy figure, dismissed by others as a symptom of mental illness. When her boyfriend, Jake, also witnesses the entity, he finally believes her. Their friend, Trevor, remain skeptical, even after encountering a mysterious woman who claims their world is connected to another realm called Alleisia. As Cassandra's visions intensify and the storms surrounding their city worsen, they are pulled into Alleisia, where they must confront the shadow man's true identity and fight to return home.
