Who was she now that George was gone?

Liza was always proud to be George's sister, but George was killed fighting in Germany. Now, all of Liza's efforts are directed to helping America win the war and punishing the people who killed her brother. She's not sure she likes the angry person she's becoming, but she doesn't know who else she's supposed to be.

Jack always saw Liza as his best friend's little sister, but now George is gone and Jack is home in Utah and missing an arm. He's not sure where he fits in the world or what waits for him after the war, but he's drawn to Liza.

Can a tragedy help them understand their own hearts, and each other?
