An otherworlder must wield human tech and ancient magic in an epic showdown for power in the fourth book of this popular fantasy-adventure series.

Justin may have started his existence as a simple college student, but fate had other plans for him. Now, as his first gray hair grows in, marking him as an elder among elven kind, he's faced with a slew of challenges. Everything he's learned--in both this life and the one before--is being put to the test.

As Justin and his closest companion, Chien, work to build machines capable of combatting a growing battalion of evil beyond the city walls, another complication arises. Justin's daughter, Adia, is coming into her own magic, and their enemies are taking notice. With a fresh target on their back, Justin must guide Adia to hone her skills, all the while brokering new alliances with ancients and elders alike.

If they're to survive the monstrous forces coming for them, they'll have to win a race against time itself. But the violent war stirring just outside the city isn't the only threat that awaits them. Indeed, danger lurks much closer to home--and when ultimate power is on the line, some will stop at nothing to claim it as their own . . .

The fourth volume of the hit progression-fantasy series--with almost 300,000 views on Royal Road--now available in paperback, ebook, and audiobook!

Tropes include: fight to survive, secret powers, and stranger in a strange land.
