Clayson Spangler turned fourteen a couple of days ago—maybe. His father keeps the exact date under a mountain of secrets. But secrets have a way of getting out.
On a tranquil evening in the Appalachians, Clayson’s solitary life crashes into his family’s impossible past: a kingdom under the Rocky Mountains; his mother enchanted to forget her own son; strange metal objects filled with magic; and his father’s most dangerous secret—mithrium—a metal strong enough to level cities.
Now, Clayson’s father is on the run, his mother is on trial for treason, and Clayson is ordered to hide in the last remaining safehold—Tungsten City. To stay out of danger, he’ll need help from his new friend, Rugnus, a master of elemental magic, and Andalynn, the sister his father had kept hidden from him.
But after years of secrets, Clayson won’t stand by as a world of enemies—both known and unknown—threatens to eradicate his family and ignite a war between the last two cities deep under the Rockies in the Kingdom of Rimduum.
