The weaver and the witch queen
(Book)

"Oddny and Gunnhild meet as children in tenth century Norway, and they could not be more different: Oddny hopes for a quiet life, while Gunnhild burns for power and longs to escape her cruel mother. But after a visiting wisewoman makes an ominous prophecy that involves Oddny, her sister Signy, and Gunnhild, the three girls take a blood oath to help one another always. When Oddny's farm is destroyed and Signy is kidnapped by Viking raiders, Oddny is set adrift from the life she imagined but determined to save her sister, no matter the cost. Gunnhild, who fled her home years ago to learn the ways of a witch in the far north, is on her way to her exalted destiny. But the bonds--both enchanted and emotional--that hold them together are strong, and when they find their way back to each other, these bonds will be tested in ways they could never have foreseen in this rich, searching novel of magic, history, and sworn sisterhood"--,Provided by publisher.
