The main character is a young woman named Lena who has been sent back in time to the year 199601 to prevent a catastrophic event from occurring. The book is set in a dystopian future where humanity has been divided into factions based on their beliefs and values. The world is facing an existential threat from an alien race known as the Xarx. The Xarx are a highly advanced species that have conquered many planets and civilizations, but they have one weakness - they cannot survive in the presence of a certain frequency of energy that is emitted by the human brain. This frequency is known as the "omega wave" and it is the key to the survival of humanity. Lena's mission is to find a way to harness this energy and use it to defeat the Xarx and save humanity. Along the way, she must navigate the complex political landscape of the warring factions and confront her own personal demons. The book explores themes of technology, politics, and personal growth, and raises questions about the nature of reality and the role of humanity in the universe.
