Kingfisher's reimagining of Snow White centres on healer Anya and her desperate attempts to cure the king's daughter Snow through entering a strange mirror world. Hemlock & Silver is a dark 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 – seeking cures for those everyone else has given up on. But 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. Nothing, that is, until she finds a secret world hidden inside a magic mirror. This dark realm may hold the key to what is making Snow sick. Or it might be the thing that kills them all...
