From Seven Seas:
In fifteenth-century Europe, heretics are being burned at the stake. Rafal, a brilliant young man, is expected to enter university at an early age and study the era’s most important field, theology. But Rafal values Reason above all else, which leads him both to the shocking conclusion that the Earth orbits the Sun, and into the hands of the Inquisition! A decade later, two members of the Watch Guild, the dour young Oczy and the cynical Gras, find a hidden stone chest that details the secrets of the universe Rafal left behind. Dare they try to change their own stars by selling the heretical texts, or would that only lead to the stake and the fire?
