Sixteen-year-old Leon Rhaine crafts impossible inventions from bursts of inspiration he can neither remember nor repeat. Few inventions work twice. Most collapse into rubble, or worse, shrapnel and flame. The havoc caused by these psychic scientific breakthroughs threaten his dream enrollment at a prestigious science institute, and the only shot he has at saving his family from a lifetime of debt.

Leon is approached by a mysterious man promising to reveal why Leon has become the instrument of creations he does not understand. As he learns more about his gift, he discovers its connection to the appearance of the peculiar and powerful Joanna Harpyr and the nightmarish monsters she hunts. Monsters that herald devastation wherever they appear.

Can Leon find a way to stop the coming cataclysmic event in his city, or will he be a pawn in an otherworldly scheme bent on the destruction of the world as he knows it?

The answers to these life-altering questions put Leon and his friends on a crash course with an ancient organization that has secretly shaped human history for millennia.
