For thirty years, Dan Wagner has been fine. A respected professor. A disciplined, guarded man with a quiet apartment and no photographs on his walls. Every Tuesday, he sits across from his therapist, Leah Lee, and tells her almost nothing at all. Then he sees an arm on television — a wave, a rolled sleeve, a tattoo he last saw when he was nine years old, standing alone at the edge of a stretch of woods. The man wearing it is the president of the country. What begins as one man's reckoning with a monster who was never punished spirals into something far larger: an alliance with a drug lord promising a kingdom, a black-market fighter jet smuggled piece by piece across a border, a nation's grief weaponized by a fabricated confession, and an uprising that will topple a government in a single, catastrophic night. Caught in the middle are the two people trying to stop him — a lonely detective and the therapist who loves him anyway, even after she's the one who turns him in. Dan's Final Battle is a story about what a wound left silent for thirty years can become — and what it costs everyone standing close enough to watch it finally break open.
