“Why the hell would she be my sister?” Oz asks. “I dunno, man.” He shrugs. “She’s blond. You’re blond. And she’s way too hot to be your girlfriend.” I stiffen. Surely I misheard. “Mallory is a chess player, man.” Oz’s tone drips disdain. Whatever antipathy he may harbor toward me, the Office Intruder, it’s nothing compared with what he feels for this guy. He doesn’t hate me, after all. I might even be his best friend. How heartwarming.
