The Maker's Metal Books in Order

Alien beings drawing their identities and power from ancient gods prepare to enslave humanity. Billionaire inventor David Montague turns his aura-reading gift toward resisting them, joining capable companions in an effort to stop the invasion before their enemies establish control.

David Montague has weakened the alien Olympian Idols and captured some of their power, but a second myth-inspired threat emerges. Building a growing circle of allies becomes essential as his campaign expands from defeating one pantheon to confronting the Asgardian Idols.

With earlier supernatural enemies checked, David Montague faces an invasion by the formidable Frost Giants. Seeking help in Odin’s domain may provide a chance to resist them, but regardless of the Allfather’s answer, David remains the immediate defense between humanity and destruction.
