In Orison, every promise becomes part of the Aethral Lattice-the invisible web of oaths holding reality together.
When those promises are broken, storms rise, memories vanish, and creatures born from betrayal begin calling people by name.
Cael Dorsai has spent years hiding from the life he left behind. Once an oathkeeper capable of seeing where promises will fracture, he now wants only to raise his three children in the quiet fields of Hearthmarch. But when a Perjury storm attacks their home and speaks his children's names, Cael is forced to use the power he swore he would never touch again.
The price is a memory he can never recover.
As the storms worsen, Cael is drawn back toward the Knights of Kannut, the oathbound order responsible for protecting the damaged Lattice. His return leads him into Highspire, a city built upon living contracts, where a powerful magistrate is using fear, forged evidence, and manufactured disasters to seize control.
To save his family and prevent another Sundering, Cael must confront the criminal Circuit he once served, uncover the truth behind his bloodline, and decide how much of himself he is willing to sacrifice.
But protecting everyone by destroying himself may be just another kind of broken promise.
The Cost of Names is the first book in The Lattice of Orison, a family-centered fantasy series filled with oath-based magic, political intrigue, dangerous secrets, found family, and the lasting consequences of every promise we make.
