The Apples of Idunn

Driven to become king. Fated to be a god. In the cold winters of an ice age, Odin was born to be a mere jarl. But Fate has staked a claim upon him. When his brother falls under a ghostly curse, a goddess offers Odin a chance to save him. If Odin can make himself king—and promise an unspecified favor—she will make him and his family immortal.
