Mother and warrior. Scholar and spy. Rebel and hero. Set in a magical world of terror and wonder, this novel is a deeply felt epic of courage and war, in which the fates of these characters intertwine - and where ordinary people become heroes, and their lives become legend.

Al MacBharrais has a most unusual job: He’s a practitioner of ink-and-sigil magic, tasked with keeping order among the gods and monsters that dwell hidden in the human world. But there’s one supernatural mystery he’s never been able to solve: years ago, someone cast twin curses on him that killed off his apprentices and drove away loved ones who heard him speak, leaving him bereft and isolated. But he’s not quite alone: As Al works to solve this mystery, his friends draw him into their own eccentric dramas.

On the streets of Boston, the world is divided into the ordinary Usuals, and the paranormal Unorthodox.

Grimshaw Griswald Grimsby is…not one of those witches.

Since time immemorial the Spires have sheltered humanity, towering for miles over the mist-shrouded surface of the world. Within their halls aristocratic houses have ruled for generations, developing scientific marvels, fostering trade alliances, and building fleets of airships to keep the peace.

Fiercely loyal to Spire Albion, he has taken their side in the cold war with Spire Aurora, disrupting the enemy's shipping lines by attacking their cargo vessels.

Minalan gave up a promising career as a professional warmage to live the quiet life of a village spellmonger in the remote mountain valley of Boval. It was a peaceful, beautiful little fief, far from the dangerous feudal petty squabbles of the Five Duchies, on the world of Callidore. There were cows. Lots of cows. And cheese. For six months things went well: He found a quaint little shop, he befriended the local lord, the village folk loved him, he found a sharp young apprentice to help out, and, best yet, he met a comely young widow with the prettiest eyes.
