A century after the War of the Ashes shattered the old world, humanity lives under the fragile protection of the immortal Cinderen—a powerful race who demand unbreakable oaths in exchange for their aid. Promises hold power, and breaking them exacts a cost far greater than death.
Evander, a cold and enigmatic Cinderen bound by a curse he refuses to explain, collects these promises like currency. His path collides with Aelys, a fierce and determined young woman whose own oath is shrouded in mystery. Drawn together by necessity but divided by mistrust, their relationship is a volatile mix of attraction, hatred, and manipulation.
Aelys has a plan: to use Evander to infiltrate the Cinderen from within and destroy them for good. But Evander’s own agenda—and the secrets he harbors—may be just as dangerous. Bound by forces they can’t fully control, the line between ally and enemy blurs with every step deeper into the mirror world where betrayal, blood, and fire reign.
As their choices unravel the delicate balance between worlds, Aelys and Evander are forced to ask themselves: How much of their humanity—or their immortality—are they willing to sacrifice?
In Ashes of an Oath, promises are forged in fire and broken in blood. The price of trust is steep, and the cost of survival might be their very souls.
