In this jaw-dropping final installment of New York Times bestselling author Dan Gutman’s action-packed series, four risk-taking friends travel back in time to record the most infamous duel in American history.

Billionaire Miss Z might be out of the picture, but a top-secret agency wants to send Luke, Julia, David, and Isabel on one final mission. This time, the Flashback Four are headed to Weehawken, New Jersey—in 1804—to videotape the fateful duel between Alexander Hamilton and Aaron Burr.

But once they arrive, the team faces a question of historic proportions: Should they capture the tragic details of the duel or try to change them?

The Hamilton-Burr Duel tells the story of one of history’s fiercest rivalries from a fun and fresh new angle.
