Sander Bree is a royal mage. Steeped in privilege, he lives a cushy life advising the king on matters of court and politics, yet still complains that he's stuck in a rut.

Rosheen Katell is a freelance mage and, with Anzu her griffin, she’s worked hard to build a reputation as a trustworthy truth seer. She never lies, never kills.

The source of their power is the Lapis Moon in orbit above. Very soon, that magic will be gone, changing their lives and their world forever. Sander must keep a promise that would have been difficult enough with magic, but is a suicide mission without it. Rosheen is forced to side with a murderous warlord, and her once-solid principles are tested and found wanting. Both will be set against one another in a war unlike anything the world has seen before, in this sweeping fantasy of magic’s ending.
