Seventeen-year-old Ailia has vowed to find out if her recurring mare dreams, of what she thinks are glimpses into her previous life, are real. In her dreams, she is married to her soul mate, and an evil Empress named Eiess pursues and kills her. Lucia, the heir of the Northlandic Kingdom, will be crowned Sun Queen - the Queen responsible for shifting the seasons each solstice. The eve before Lucia's eighteenth birthday and coronation, Eiess storms the castle, taking Lucia and her Father prisoner. Eiess immediately instigates the prophesied three-year winter before the end of Midgard when she usurps the throne. One day, and unbeknownst to her - nearly two years later - Ailia wakes up in a glacier cave cold, beaten, and far away from home. She doesn't remember how she ended up there or even that she was abducted by the ruthless Vikings. When a healer named Soren rescues her, Ailia can't help but think that she knows him from somewhere, and that they were fated to meet - and destined to fall in love. And when Ailia, Lucia and Soren discover a shocking secret that intertwines their destinies, one of them betrays the other two - a betrayal that ultimately puts their lives, and the lives of humanity, in which they had sworn to protect, in grave danger.
