This story is a mystery sci-fi novel. It's a story that relates with the world, time, and the universe. It's canon to most of the other stories that I'll write as well.
But this one is special because it the first one to hint clearly at the other universes.
To summarize, the story follows multiple characters, but the main one among those characters is Eric Brander, a middle aged accountant without a past. He has amnesia, but continues living his life as we all do.
The story really begins with a phone call that our main character receives in the middle of the night. The moment he answers that call, the mysteries of the world reveal themselves to him, and so many plots and characters reveal themselves in the story.
Eric struggles to survive assassination attempts, time loops, crisis, paradoxes and the ever looming fact that he may be the cause of the end of the world, possibly the universe.
