Just in case

What if Fate were out to get you? The day David Case saves his brother's life, his whole world changes. Suddenly, every moment is fizzing with significance, full of what ifs? He must hide, become an entirely new person to escape Fate ... if he can. Will changing his name, befriending an astrophysicist and gaining an imaginary pet be enough? Bewildered and obsessive, he'll try anything to survive. Suggested level: secondary.
