“Toby.” A brief pause. “Don’t even try. You really expect I would give that sorry excuse to Jason? The software patch we sent out to fix the frame- rate problem made everything worse and now people are raisin’hell ’cause they got weapons malfunctioning and dragons flying ass- backward. You’d better come up with some kinda brand- new patch to fix it, or . . . hold on.” Another cell phone went off, and she grabbed it out of a bag slung over her shoulder. “Yeah,” she said into the second phone. “I got the asshole on the other line, trying to convince me everything is all MoonPies and salted peanuts.”
