Gerda, Jonathan and the Magical Crystals
An epic adventure across worlds, legends, and destiny.

Gerda and Jonathan are ordinary teenagers living in a quiet town near London - until strange dreams begin to haunt them. Dreams of a burning world, a one-eyed warrior, and a forgotten war among the stars.

When the twins discover mysterious glowing crystals hidden in their attic, their lives change forever. The crystals awaken powers buried deep within their bloodline and reveal a truth their father has kept secret: they are the last descendants of an ancient civilization - the Aesir of Asgard.

As long-forgotten enemies rise again, Gerda and Jonathan must learn to use their abilities, travel through incredible realms, and uncover the secrets of their heritage. Guided by Odin's legacy and hunted by forces of darkness, the twins are thrust into a battle that will decide the fate of worlds.

But they are still just teenagers...
And the war for Asgard has only begun.
