Book VI in the "King of the Trees" series. Welcome to Mapleton, a sleepy Thalmosian village where people earn their living tapping maple trees to make syrup and candy. Kyleah's father, Branagan, is Mapleton's sugarmaster. However, beneath the village's placid facade festers a terrible secret. One spring day, Kyleah and her brother, Barley, are helping their father in the sugar bush when Kyleah discovers a sword jutting out of a maple tree. By removing the sword, Kyleah unwittingly opens a door that cannot be easily shut again and rekindles an ancient rebellion. The key to quelling the revolt lies in finding a perfect mirror, a quest that leads Kyleah through water and fire in search of the fabled firebird. In becoming the very enemy she dreads, she learns to trust the King when all seems lost. Ultimately, she finds strength in her weakness and weakness in her strength.
