The Witch's Heart by Genevieve Gornichec

When a banished witch falls in love with the legendary trickster Loki, she risks the wrath of the gods in this moving, subversive national bestselling debut novel that reimagines Norse mythology.

Angrboda's story begins where most witches' tales end: with a burning. A punishment from Odin for refusing to provide him with knowledge of the future, the fire leaves Angrboda injured and powerless, and she flees into the farthest reaches of a remote forest. There she is found by a man who reveals himself to be Loki, and her initial distrust of him transforms into a deep and abiding love.

Their union produces three unusual children, each with a secret destiny, who Angrboda is keen to raise at the edge of the world, safely hidden from Odin's all-seeing eye. But as Angrboda slowly recovers her prophetic powers, she learns that her blissful life--and possibly all of existence--is in danger.

With help from the fierce huntress Skadi, with whom she shares a growing bond, Angrboda must choose whether she'll accept the fate that she's foreseen for her beloved family...or rise to remake their future. From the most ancient of tales this novel forges a story of love, loss, and hope for the modern age.
