After the harrowing events in Tartarus, Cali's life has changed forever. She now knows she is an Immixtus, a rare being with the power to alter the fabric of reality itself. But with great power comes great danger. Chaos, the malevolent force bent on destroying the world, looms ever closer, and the prophecy foretelling her rise remains shrouded in mystery. Determined to stop Chaos, Cali, along with her loyal friends Blythe and Maechon, embarks on a perilous journey to the North. Their quest: to find the second gift in the ancient Treaty between the Realms. But the path is fraught with challenges, not least of which is a band of fierce Vikings led by the young and ambitious Ein. Ein harbors a deep-seated hatred for the gods, particularly Odin, and his intentions are as unpredictable as they are dangerous. As Cali navigates this treacherous landscape, she uncovers shocking truths about the Vikings and the gods of Asgard. What she learns will challenge everything she thought she knew about her powers and her destiny. With enemies drawing nearer, Cali must confront her own inner turmoil and the unsettling reality that her abilities are not as under control as she had hoped. In "Borealis," the second installment of the Immixtus Series, Cali's journey takes her to the edge of her limits and beyond. Faced with betrayal, revelation, and the ever-present threat of Chaos, she must find the strength to harness her powers and protect the world from impending doom
