HARVEY asked on Thursday afternoon as they crowded into Sophie’s bedroom. The minute they shut the door behind them, Sophie conjured up a packet of Oreos and three cans of Diet Coke, while making a mental note to hide the trash from her mom. “Yeah, because I’ve heard that prolonged exposure to Melissa Tait can make you break out in hives,” Kara chimed in from where she was sitting cross-legged on Sophie’s yellow-and-white comforter, hugging a shopping bag to her chest. “I’m talking about whether Sophie’s had any after-effects from all the flying she did yesterday,” Harvey corrected her as he reached for a cookie and started to pull it apart, which was his preferred way of eating them. “And I’m talking about the fact that Melissa can’t be trusted, so if she was nice to Sophie, then it was for a reason. Oh, and did you see her today at school? All that smiling and waving? Something’s definitely going on.”
