Sixteen-year-old Kellan DuCuivre is the descendant of traitors. She never knew her family members or which one of them betrayed the isle of Nanseau. But like all Du orphans after the war, Kellan is forbidden by law from practicing makecraft, the trade of carving magic into metal that was perfected by the Guild of Engineers and their maker apprentices.

No one can know that Kellan has been using makecraft in secret and that, in the wake of a tragic miscarriage, she’s been helping her adoptive father, Edgar, run his celebrated makeshop. But Edgar’s condition is worsening, and his shop is on the brink of ruin.

On the eve of the Eighty-Fourth Annual Makers’ Exposition in Nanseau’s sparkling city of Riz, Kellan is thrust into the Guild’s twisted web of political intrigue and ancient secrets when she strikes a dangerous deal with one of its members to save Edgar and his shop. Now Kellan must compete in a rigorous gauntlet against the nation’s elite for a coveted spot as a maker’s apprentice. But danger lurks at every turn.

And as Kellan falls into a budding relationship with the illegitimate son from one of Nanseau’s most revered families, she’s put into the limelight when something sinister begins targeting the Gauntlet’s competitors and wreaking havoc on Riz. Amid a crumbling city and a ticking clock, winning the Gauntlet won’t just be a test of survival—it will mean pulling back the veil of secrets behind the Guild and uncovering the shrouded legacies of Nanseau itself.
