It is year 1815. On the verge of adulthood, sisters Shannon and Dana are visiting their wise, old grandmother in Wales on a very special day, and finally learn why their life has been strangely affected by something they have not previously understood. That day, a harrowing creature of the Nine Worlds calls out for special, talented humans of the Tenth world. Our world.

Dana performs an irreversible deed that opens the gate to the strange world of Aldheim, and they meet the strange creature calling for them. In this world they find their true calling, their special talents, the truth of the gods and also a world of mystery, cruelty and adversity. Shannon and Dana struggle with their previous relationship as one grows cruel and power-driven, while the other learns to value friendship. Much is demanded of Shannon, who is struggling with her loyalties.

Despite the many dangers and their apparently hopeless situation in the new, dangerous world, there is hope, for Shannon has some special, coveted powers of healing, reserved to the chosen of the gods. If she perseveres, she can change the past and bring back even the gods.

But the price will be great.
