When Sara heard the words 'who killed the Normans', she thought of a trick of her imagination, but when she saw Algowagh waiting for her at the end of a corridor, she realised that it was something more than just imagination. Algowagh—whose name was barely pronounceable for Sara—told her about Parallel Dimensions, Betwixt Doors, Big Empty and a frightful Spatial-Temporal Abyss erasing the History of the Worlds. Nothing of what Algowagh said was clear to her, except that she was a key element in the mission to rescue the System—the whole of all existing worlds.

That is how Sara got involved in a journey through three different worlds and towards the city of Fjunur—the heart of the System—to find out what exactly did happen to the Books of Worlds, where the History of the System is kept, and how to stop the Spatial-Temporal Abyss from destroying the entire System.

Sara and Algowagh won’t be alone in the journey. Faewal, a warrior princess from Algowagh’s same dimension, and Huydai, a rebel hunter from a primitive world, will join them, and together they will face all sort of challenges leading them to an unpredictable truth. And to an expected ending, that might be just the beginning.
