The Phase Transition by Ryan Okerlund

For millennia humanity has fought against the notion of magic. Superstition and irrational fear have slowly been replaced with reason and logic. This was our downfall. For science and magic are merely transitory fluctuations our planet has experienced a thousand times in its history. As has happened in the past, so must happen again. As the Phase sweeps over the earth, America is lost in chaos. Electricity and gunpowder become useless, and anarchy rules. From amongst this pandemonium strikes forth an ancient from the dark past who strives to create order in the bedlam of the present. Professor Avedesh gathers those he knows to have the magical strength of the ancients; those whose very genes carry power. Fighting off starvation and shadowy cults that pursue them, the Professor must teach his followers to use their latent powers, not only to save themselves, but civilization.
