Her Radiant Curse by Elizabeth Lim

I received an ARC of this book. I didn’t know if I was gonna like this one, but I really did. I didn’t realize, but it’s a prequel to Six Crimson Cranes, though it can be read as a standalone. Channi will protect her beautiful sister Vanna at all cost. Channi has the face of a snake, and poison runs through her veins. Vanna is the most radiant girl in the land, a bright golden light emanates from her. Channi wasn’t born a monster. To save her mother’s life, her father sacrificed her as a small child to the Demon Witch, who feeds off children. But instead of killing Channi, she cursed her, with a promise to return on her newborn sister’s seventeenth birthday…and kill Vanna. Channi, seventeen years later, has trained nearly her entire life to protect Vanna, who’s being auctioned off. But Vanna will become a queen, and Channi a prisoner. With the help of her best friend, a snake named Ukar, and a handsome half-dragon, Channi must travel across the land to save her beloved sister from the Demon Witch.
