Here is the summary of the book:
Meet two teens whose worlds are about to change forever in this paranormal Young Adult novella, a prequel to Ink by debut author Amanda Sun…
Katie Greene’s worst nightmare comes true when her mother dies, and she’s devastated to learn that she will have to leave the only home she’s ever known. Desperate to find where she belongs, she must decide if she has what it takes to start a new life across the ocean.
For Yuu Tomohiro, every day is a nightmare. He struggles to control his strange ability, and keeps everyone at a distance so they won’t get hurt—even his girlfriend, Myu. At night, a shadow haunts his dreams, and a mysterious woman torments him with omens of death and destruction. But these haunting premonitions are only the beginning…
Shadow comes before INK in order. Alternating between Tomo-kun and Katie's point of views, a chapter each setting the stage to INK, the first book to the Paper Gods series. Sort of like a filler story with the events relating to and what happened after Katie's mother died and what made her decide to finally go to Japan to live with her Aunt Diane.
With Tomohiko, the shadows are ever circling him, his Kami blood needing out. His side of the tale pertains to his breakup with Myu, an act of sacrifice he performs in order to keep her safe from his demons. And the events of INK that lead to Katie and Tomo's first meeting. The author keeps it simple and basic but interesting enough for those who begin with this novella and then move onto the first book.
