Aelthiron

Thirteen-year-old Stephen Browns has a dangerous secret: he cannot feel physical pain. What everyone considered a medical disorder becomes his only hope for survival when monsters suddenly invade Earth.

After an ancient gravity stone fuses to his chest, Stephen is introduced to a hidden world of galactic sorcerers, "Gentrix" warriors, and inter-galactic rivalries. Alongside his best friends, Zach and Hezides, Steph must save the multiverse from a dark emperor determined to conquer everything. As the "Chosen One" of a prophecy he doesn't fully understand, he must master his gravity-defying abilities before it is too late.

He is the only thing standing between the multiverse and total destruction. Stephen cannot feel a blade or a burn, but the weight of the world is a feeling he can't escape.
