The lost Volsik heir has finally returned to the people of Íseldur, and even with the warrior who's captured her heart standing by her side, Silla's task is monumental. She must earn the loyalty of the northern jarls to drive Ivar Ironheart from the throne and restore peace in the kingdom. But the secret she guards vigilantly threatens to ruin all her plans: a shard of a god lives in her mind, twisting her thoughts and deeds to His will.

Meanwhile, held captive on the mysterious Isle of Zagadka, Saga Volsik fights to return to her sister in Íseldur. But when King Ivar sets his sights on the Zagadkians, she's forced to make an impossible choice: fight for the man who stole her--and is now hellbent on marrying her--or let the innocent people of his kingdom die.

As a poisonous mist threatens the realm, the sisters will delve into the unknowns of their magic to battle against evil. Return to the land of ice and fire, where a god awakens, a queen finds her power, and sisters must unite against the darkness threatening their realm.
