Hemlock & Silver By T. Kingfisher

A sinister reimagining of Snow White steeped in poison, intrigue, and treason of the most magical kind

Healer Anja regularly drinks poison―not to die, but to save. She is seeking cures for those everyone else has given up on. One day, a summons from the king interrupts her quiet, herb-obsessed life. His daughter, Snow, is dying, and he hopes Anja’s unorthodox methods can save her. Aided by a taciturn guard, a narcissistic cat, and a passion for the scientific method, Anja rushes to treat Snow, but nothing seems to work until she finds a secret world.
