Join Astrid Xu in this action-packed adventure as she ventures into the world of mythological China in order to save her mother -- and the world! Perfect for fans of Rick Riordan and Shang Chi and the Legend of the Ten Rings ! When Astrid Xu stumbles upon an ancient scroll with Chinese characters, she just knows it's the key to saving her mom from the "fog"--the depression that keeps her mom bedridden for days at a time. What Astrid doesn't expect, though, is to be transported--along with her younger sister, Marilla--to Zhen, a realm where the Chinese legends of old are real! In Zhen, Astrid and Marilla meet Erlang Shen, a powerful warrior, and Lan Caihe, one of the Eight Immortals. It seems an ancient evil known as Chaos is wreaking havoc all throughout this mythological world, threatening to shroud all of Zhen in darkness--and Astrid is the only one who can stop it. With only her sister (who has been trapped in the body of a cat!) and two great mythological figures to help her, Astrid sets out on a journey to face her destiny. But will she be able to save her mom--and the world!--before Chaos reigns supreme?
