In "Hemlock & Silver" by T. Kingfisher, healer Anja is summoned by the King to save his dying daughter, Snow, using her unorthodox methods involving poison. As Anja delves into a dark realm hidden inside a magic mirror, she uncovers secrets that could either cure Snow or doom them all. This dark reimagining of Snow White is filled with intrigue, magic, and a fantastic cat, making it a delightfully offbeat fantasy read.
