Light (Gone, #6)

by Michael Grant

Caine stopped, turned around, and walked back to him. Sam was struck by the undeniable fact that even now, even after being beaten and humiliated by Penny, his brother could project that hard-to-define thing called charisma. Evil, yes, but a tall, handsome, charming kind of evil. “Why are we doing this?” Caine asked him. “You know damned well why we’re doing this. Because it’s a fight. It may be the fight. It may be the final fight. And what else are we good at, you and me? What are we going to do if we ever get out there anyway? You going to sign up for some AP classes? Get your college essay started? Take driver’s ed?” Caine laughed, laughing at himself, it seemed. “Yeah, I’m pretty sure Harvard will want me. I mean, how many former kings do they have applying?” Sam tried to stop himself asking, but in the end he blurted it out. “And Diana?” “Great body,” Caine said breezily. “And a very open mind.” Sam didn’t buy it. “It’s more than that, you and her.” Caine didn’t answer, which was all the answer Sam needed.

This reminds me of Jake & Rachel's conversation in Animorphs, about what in the world they're going to do when the war is over, and how they can't imagine real life and being anything but fighters.
