Kaybree has grown up hearing stories of the Angels, mythical beings who used to defend Nordgard from the creatures of the forest. After leaving mankind without guidance for centuries, they returned fifteen years ago, leaving a fiery swath of destruction.

When Kaybree is called to the outpost by the forest, home to her mother's mysterious Vormund Order, she stumbles into the latest Angel attack. Soon she learns that she has the unique power to fight them: the ability to transform into a radiant being of fire and lightning.

As she delves deeper into her mother's organization, though, she starts to wonder: why would Angels, holy messengers of God, attack people? Every answer she finds only sparks more questions. Because Vormund holds a deadly secret—one that could change Nordgard and the human race forever.
