Awakening — Kevin D. Miller

A megalomaniac god is pursuing a millennia-old vendetta, and Leif must learn to wrangle a newly awakened power to either become a hero or a villain. He will leave his old life and run from creatures he believed were reserved for myth and legend. He travels across the realms while struggling to tame the blinding rage that comes with his new demi-god like power. Will Leif survive the intra-realm quest and prevent Ragnarok or will he fail to control his awakening?
