The Witch's Heart is a novel that reimagines the Norse myth of Angrboda, a giantess and witch. Banished to a remote forest, she falls in love with Loki, the trickster god, and bears him three monstrous children: a wolf, a serpent, and the goddess of the underworld. After the gods learn of her powerful and dangerous offspring, Angrboda must fight to protect her family and defy the fate that threatens to destroy them. The book is described as an epic and engrossing story of love, survival, and a mother's fierce devotion, transforming faceless names of myth into sympathetic, living characters.
