Professor Bob Mcleod must adapt, advance and apply the lessons learned in Thor's Apprentice when he and his colleagues learn the on-demand weather technology they discovered and brought to the United Nations is anything but new.

After discovering who this technology came from and when, a new alliance of scientists, military, government and United Nations officials set out to complete the work Doc Auster began through a new operation called Thor's Journeymen.

Professor Mcleod and fiancé Ann find themselves at the center of a new storm; an undeclared "weaponized-weather" arms race between world powers and a stated global philanthropic objective to safely and equitably field weather on-demand for the benefit of all.
