Warning: Very detailed novel - read prologue for a taster.

A single hypothesis was all it took to initiate a triad of young geniuses to try their hand on a theory of magic. But be it as they try to peer into the preternatural abyss of this unknown world, a satellite plummets from the exosphere – their lives come to a sudden end. In death, they reincarnate into a macrocosm abundant with magic, living their lives oblivious of their past. That is, until the age of 8 when they regain their memories as a wakeup call to reality. Upon cognizance, they reach out in search of their dear ones from Earth while unravelling the mysteries of the universe.
