The book of bera

Born and raised in a stark, coastal village on the shore of the Ice-Rimmed Sea, Bera is the daughter of a Valla, the Vikings' most powerful seers. But her mother died when she was young, leaving Bera alone with her gift, unable to control her feckless twin spirit or understand her visions of the future.

When this inability leads to the death of her childhood friend at the hands of a rival clan, Bera vows revenge. And learning that her father has sold her into marriage with the murderous enemy's chieftain, she is presented with an opportunity even sooner than she had hoped...

As her powers grow stronger, her visions of looming disaster become more and more ominous until she is faced with the ultimate choice: will she exact vengeance? Or can she lead her people to safety before it's too late?
