About This Book
Michael Grey sits at his desk, crunching numbers, when suddenly everything he's known feels like a lie. Memories vanish, secrets bubble up, and the agents watching him aren’t just ordinary spies—they’re hiding a cosmic truth that could change everything. What happens when an ordinary life hides an extraordinary alien power?

This graphic novel blends fantasy, science fiction, and humor with themes of identity and romance, suitable for readers ages 9-12.
