Tristan and Evelyn

Tristan was born two years, two months, two days, two hours, two minutes and two seconds before his little sister, Evelyn. but they might as well have been twins.

Tristan skateboards to Greenleaf Elementary every day with Evelyn walking beside him, and he carries her lunch in his backpack because that's what an older brother should do for his little sister.

Tristan caught one of his fellow seniors making fun of Evelyn because of her bookish personality, unremarkable looks, modest clothing and, for his trouble, Tristan caught a right hook bloodying his nose, earning a trip to the nurse and catching a 3-day suspension for fighting.

Evelyn's vice president of the senior class, has a 3.7 GPA, and lives to read Tristan's letters about him and his Marine buddies, overseas.

A Navy chaplain and Marine Corps captain just left the house.

Tristan and Evelyn are lost.
