When his mother became President, Alex Claremont-Diaz was promptly cast as the American equivalent of a young royal. Handsome, charismatic, genius―his image is pure millennial-marketing gold for the White House. There's only one problem: Alex has a beef with the actual prince, Henry, across the pond. And when the tabloids get hold of a photo involving an Alex-Henry altercation, U.S./British relations take a turn for the worse.
Heads of family, state, and other handlers devise a plan for damage control: staging a truce between the two rivals. What at first begins as a fake, Instragramable friendship grows deeper, and more dangerous, than either Alex or Henry could have imagined. Soon Alex finds himself hurtling into a secret romance with a surprisingly unstuffy Henry that could derail the campaign and upend two nations.
