Carving Shadows into Gold by Brigid Kemmerer

Dangerous magic. Fateful choices. Broken promises. The spellbinding series by New York Times bestselling author Brigid Kemmerer continues.

The King’s Courier Tycho has made a treacherous bargain. Now beholden to the magical scraver who saved King Gray’s life, one false move could end everything.
Jax escaped his life in Briarlock and traveled with Tycho to Emberfall. But life outside his small village brings unexpected challenges–and unlikely adversaries.
After years of hating the royal family and their magic, Callyn never expected to be at the Queen’s side, with magic on her fingertips. But at the royal court, she can’t trust anyone–including the man she thought she loved.
Cast apart, Tycho, Jax, and Callyn must learn to wield the magic that is dividing their kingdom. As the magical scravers attack from the north and the king’s rivals gain strength, time is running out.

War is looming. Love is tested. And magic could be the only answer. . .
