Sixteen-year-old Jae Hwa Lee is a Korean American girl with a black belt, deadly aim, and a chip on her shoulder the size of Korea itself. When her widowed dad uproots her to Seoul from her home in L.A., Jae thinks her biggest challenges will be fitting in at a new school and dealing with her dismissive Korean grandfather. Then she discovers that for centuries, a Korean demigod named Haemosu has been stealing the soul of the oldest daughter from each generation in her family. And she is next on the list. But that's not Jae's only problem. There's also Marc. Irresistible and charming, Marc threatens to break the barriers around Jae's heart. As the two grow closer, Jae must decide if she can trust him. But Marc has a secret of his own, one that could help Jae overturn the curse on her family for good. It turns out that Jae's been wrong about a lot of things: her grandfather is her greatest ally, even the tough girl can fall in love, and Korea might just be the home she's always been looking for.
