A PRINCESS. A SPY. A THREAT.
When the Indigo Kingdom conquered her homeland, Wilhelmina and other orphaned children of nobility were taken to Skyvale, the Indigo Kingdom's capital. Ten years later, they are the Ospreys, experts at stealth and theft. With them, Wilhelmina means to take back her throne.
But wraith, a toxic by-product of magic, pours across the continent, reshaping the land and animals into fresh horrors. Soon it will reach the Indigo Kingdom. Wilhelmina's magic might be the key to stopping the wraith, but if the vigilante Black Knife discovers Wil's magic, she will vanish like all the others.
