The last fallen star

Summary: Riley Oh can't wait to see her sister get initiated into the Gom clan, a powerful lineage of Korean healing witches their family has belonged to for generations. Her sister, Hattie, will earn her Gi bracelet and finally be able to cast spells without adult supervision. Although Riley is desperate to follow in her sister's footsteps, she's a saram -- a person without magic. Riley was adopted, and often feels like the odd one out in her family and the gifted community. Then Hattie gets an idea: what if the two of them could use an incantation that would allow Riley to share Hattie's magic? They decide to perform it at Hattie's initiation ceremony. But when the sisters attempt to violate the laws of the Godrealm, Hattie's life ends up hanging in the balance, and to save her Riley has to find the last fallen star. But what even is the star, and how can she find it? As Riley embarks on her search, she finds herself meeting fantastic creatures and collaborating with her worst enemies. And when she uncovers secrets that challenge everything she has been taught to believe, Riley must decide what it means to be a witch, what it means to be family, and what it really means to belong.
