English Summary/英文概要： France, October 1944. A Japanese American war hero has a secret.

A secret so awful he’d rather die than tell anyone--one so entwined with the brave act that made him a hero that he’s determined never to speak of the war. Ever.

Decades later his son, Daniel Tokunaga, a world-famous cardiac surgeon, is perplexed when the U.S. government comes calling, wanting to know about his father’s service with the 442nd Regimental Combat Team during WWII. Something terrible happened while his father was fighting the Germans in France, and the Department of Defense won’t stop its investigation until it’s determined exactly who did what.

Wanting answers of his own, Daniel upends his life to find out what his father did on a small, obscure hilltop half a world away. As his quest for the truth unravels his family’s catastrophic past, the only thing for certain is that nothing--his life, career, and family--can ever be the same again.
