Nine-hundred thousand years ago, Althesal and her six friends from the multi-galactic Union of civilizations discover a mysterious Time singularity on planet Earth of the Sol System. The singularity is at the center of an unconventional library - a complex of gardens with light-made spirals where records of the past, the present and the future of Humans are stored. Why is this place on Earth? Who built it? The Time singularity is an enigma... it appears to be both a technology from an advanced civilization and an expression of art to inspire the soul. But the singularity is broadcasting a Call, and the seven are not the only ones who have answered it. Obscure Powers from beyond the many worlds of Galactic Humans are also interested in it and will not stop until they control it. Thus, the seven must make a choice, a choice that will not only affect their evolutionary future but the destiny of Earth itself. The Call of the A�din Planet is the first book in a series of stories of Earth that tell of the unusual origin of our Humanity and the bonds which link us with the many civilizations in our region of Space that scientists call "the Local Group of Galaxies". The A�DIN HORIZON story universe, using visionary science fiction and action adventure, takes us beyond the conventional understanding of Space, Time and extraterrestrial civilizations, and explores new dimensions of what it means to be Human, not only on Earth but in the Universe as well.
