The Progenitor's Path: Book 1

Jace's 21st birthday is followed by what he originally thinks to be the worst hangover he's experienced to date, but actually turns out to be the awakening of magical powers not seen within his family for generations.

His one and only friend from college endeavors to teach him about the true nature of not just the world, but his magic powers, all while introducing him to the various portals that bridge the gap between their world and other mystical realms.
