It's spring break, and 14-year-old Hannah Anderson is spending it with the "Coast-Is-Clear" program, a group committed to cleaning Pacific Rim National Park Reserve's beaches of debris that has drifted across the Pacific from the tragic Japanese tsunami of 2011. Soon after Hannah arrives, Jack, her raven sidekick, discovers something washed up in the surf: a luminous glass ball marked with a strange Japanese character. Immediately, unusual things start to happen, beginning with the arrival of "Kimiko," a Japanese girl with a secret past. Kimiko, it turns out, is part spirit fox (kitsune) and is here to reclaim the source of her power — the glass star ball she lost in the tsunami. Even with her star ball, however, Kimiko's magic is dangerous and unpredictable, and hiding her true identity proves a challenge. But Hannah knows the truth, and with the help of Jack and a mysterious wolf waiting in the forest's shadows, she is determined to help Kimiko find her place in the world.
