In a world divided into four rival Dominions, power is everything-and Rubi Morningtail has almost none. Three years after the Annihilation destroyed her homeland and shattered her memories, she lives as an Azure refugee in the Dominion of the Silver Tyger, scraping by as a ribbon dancer and hiding her little bit of singing magic. When she wounds a massive battle-tyger on her doorstep, she draws the notice of Blake Axefire- supreme metal mage, leader of the royal tyger warriors, and the last man an Azure should trust. His sentence? Cast her into the Bonding, a brutal trial where tygers choose their riders and slaughter the rest. Surviving is unthinkable.

But survive she does. Now she’s stuck on Blake’s elite team racing to reseal the Anchors to the demon realm. With rebels striking, demons rising, and the Dominions at each other’s throats, Rubi must unlock the truth of her magic and her past…while resisting her dangerous attraction to the ruthless warrior who could be her redemption-or her ruin.
