“ Of the Phoenix kids, the one Derek got along best with was Daniel. In him, Daniel had found a good sparring partner. And a plotting partner, too. Derek wasn’t just the biggest and strongest in our group. He was also the smartest. Scary, off-the-charts smart. That intimidated Daniel a little at first—he’s bright, but he needs to work for his grades. But Derek wasn’t a show-off or a know-it-all, so they got past that and we would hang out together, the two guys, Chloe, and I planning and plotting our future, bouncing ideas off one another. ”
