Barclay and his friends race to find a legendary beast in the Wilderlands before their enemy in this action-packed fourth book in the New York Times bestselling Wilderlore series. As the election for Grand Keeper looms closer, the villainous Audrian Keyes returns. He claims he has the secret to finding Navrashtya, the Legendary Beast of the Tundra who's been missing for centuries. And so a team of specialized Lore Keepers must undertake a desperate mission: find her first, no matter the cost.

But the uncharted regions of the Tundra hold countless dangers, from the monstrous Beasts to the brutal cold, yet far more chilling mysteries await them out on the ice caps. Like why Navrashtya went missing in the first place. Or the truth behind this strange Lore that only Barclay can feel, whose power might very well save the mission--or doom it.
