Abstract: A series of strange meteors enters a planetary system, and a world is in danger. Can space travellers from this world, travel in time and space, and return in time with the technology needed to avert the disaster? This is the first book of the Orthogonal trilogy, following the travellers on their mission.
Contents: On the farm where she lives, Yalda sees strange meteors that are entering the planetary system at an immense, unprecedented speed -- and it soon becomes apparent that more of this ultra-fast material is appearing all the time, putting her world in terrible danger. An entire galaxy is about to collide with their own. There is one hope: a fleet sent straight towards the approaching galaxy, as fast as possible. Though it will feel like weeks back home, on board, millennia will pass before the collision, time enough to raise new generations, and time enough to find a way to stop the ultra-fast material. Either way, they have a chance to save everyone back on the home world.
