Sally Jenkins is finally getting used to things. After the whole saving the world fiasco cooled down, life continued as usual. She and her friends went back to their regular lives and dealt with tests, quizzes, teachers, and other teenager-esque things, but she still couldn’t shake the feeling their work wasn’t quite finished yet. This feeling is confirmed when she is chased down by a mysterious stranger who seems to know more about her and her friends than they do about themselves. With a great evil growing and a new danger introduced, they’re hurled into a whole new mystery, and this time around, the stakes are raised. Just when they thought the adventure was over, a new one began.
