The Waking of Angantyr

Bondsmaid. Berserker. Bane.
Hervor is no stranger to hardship. Not only is she a reviled bondsmaid, but she's haunted by the ghosts of dead men. When a berserker fit turns her into a murderer, she has nothing left to lose: fleeing everything she's known, Hervor goes to find a new future and a way to silence the past.
Her quest will take her from the viking seas to the depths of a witch's forest, from frozen mountains to a king's golden hall. But the road ahead is no less bloody than the one behind, and the foul magic Hervor fears most is the only thing that can lay her ghosts to rest.
They say when you seek revenge, you should dig two graves, but Hervor might be able to get away with one. Because the voices of the dead are getting stronger . . . and her greatest enemy may be herself.
