When sixteen-year-old Gabriel Lazris, an American in Santiago, meets Caro Ravest at a party in 1973, something clicks. They fall fast, but with everyone saying there's going to be a coup - and no one saying it louder than Gabriel's Nixon-loving father - Gabriel is afraid his parents will force him to return home. But to Gabriel, Chile is home.

Decades later, Gabriel's American-raised adult daughter Nina heads to Buenos Aires in a last-ditch effort to save her dissertation. She quickly gets sidetracked: first by a sexy professor, then by a controversial book called Guerra Eterna. A document of war and an underground classic, Guerra Eterna destabilises Nina's identity and drags Gabriel's past into the light.
