While Amberle embarks on a deadly task to prove her worth to the Ellcrys, the Dagda Mor sends the Changeling, an ancient, shape-shifting Demon, to kill her and anyone in its way. But when a demon can take shape of anyone in the palace, finding it won’t be easy.

Amberle, Wil and Eretria are forced to overcome their differences to survive the perils of their quest, including the nightmarish Reaper. At the palace, Ander attempts to recruit help from an unlikely ally to find the Dagda Mor - his brother’s murderer, Slanter, a Gnome assassin.

On the run from the relentless Reaper, Amberle, Wil and Eretria take shelter in Pykon, a snowy Elvin outpost that houses a grisly secret. Meanwhile, Ander and Slanter make a devastating discovery about the Dagda Mor’s forces.

Wil and Amberle desperately search for Eretria to save her from the vicious elf hunters who kidnapped her. Little do they know, she’s stumbled upon a secret settlement of Humans and may finally feel like she belongs. But their utopia is much more than meets the eyes. Meanwhile, Allanon must inspire Ander to accept his destiny.
