Farther out—perhaps a couple of miles—a third boat rocked in the waves. She wouldn’t have noticed it at all, but a flickering light was coming from it. It was hard to judge size, given the distance, but it seemed larger than the other two boats. It was painted a brilliant white color—since the sun was behind her, it was reflecting light marvelously. The flickering light was obviously a signal of some kind: it was not unlike the signals the unicorn guard and pegasus guard were exchanging before she left the reservoir.
