Twelve has become a hunter and chosen a new name to reflect her elemental power: Phoenix. Three months after the destruction of the Hunting Lodge, a witch arrives from the frost palace of Icegaard, desperate for Phoenix’s help. Icegaard is in grave danger from an evil force called the Shadowseam, and if the witch-palace falls, all the clans of Ember will fall with it. Travelling north, Phoenix and her friends, Five, Six and Seven, must battle frightening new monsters and find a way to defeat the Shadowseam. But as Phoenix learns to control her new power, the faceless Croke begins to haunt her dreams... Phoenix will have to fight with everything she’s got to save Ember from mortal danger. But the price of survival may be more than she can pay.
