In Viking times, Norse myths predicted the end of the world, an event called Ragnarok, which only the gods could stop. When the apocalypse comes, the gods must battle wolf monsters the size of the sun, serpents spanning the seabed, all bent on destroying the world. The gods died a long time ago. Matt Thorsen knows every Norse myth, saga and God, because this is his family's story . Most people in the modern town of Blackwell, South Dakota are essentially descendants of either Locke or Thor, including Matt's classmates Fin and Laurie Brekke. However, knowing the legends and fully believing in them are two different things. When the rune readers discover that Ragnarok is near and the children, led by Matt, will stand for the gods in the final battle, he can hardly believe it. Life will never be the same for Matt, Laurie and Fin as they assemble an unstoppable team to prevent the end of the world.
