Sixteen-year-old Jae Hwa Lee is a Korean-American girl with a black belt, a deadly proclivity with steel-tipped arrows, 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 to a new school and dealing with her dismissive Korean grandfather. Then she discovers that a Korean demi-god, Haemosu, has been stealing the soul of the oldest daughter of each generation in her family for centuries. And she's next. 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.
