Before the world ended, the gods were afraid. Not of distant enemies or unknown forces, but of three children born in the dark forests of Jotunheim, fathered by a god who sat at Odin's own table. A wolf that could not be contained. A serpent that encircled the world. A ruler of the dead who would one day command an army of everyone who had ever lived. Loki's children were not accidents of fate. They were its instruments. Loki's Children: Monsters, Myths, and the Norse Prophecy of Asgard's Destruction traces the full arc of Norse mythology from the world's violent creation to its prophesied ending, following the three figures at the center of the most ambitious and honest cosmological vision the ancient world produced. Drawing on the Poetic Edda, the Prose Edda, and the rich tradition of Norse mythological scholarship, this book explores how Fenrir, Jörmungandr, and Hel were not villains but forces, each one a necessary consequence of the world the gods had built and the fears they could not overcome. This is the story of a cosmos that knew it was going to end and kept going anyway. It is the story of gods who prepared for defeat with the full commitment of those who understood that how one faces the inevitable matters more than whether it can be stopped. It is, ultimately, a story about fate, courage, and the kind of honesty that only mythology can deliver.
