When fifteen-year-old Krystal Bentley moves to Lincoln, Connecticut, her mom's hometown, she assumes her biggest drama will be adjusting to the burbs after living in New York City. But Lincoln is nothing like Krystal imagined. The weirdness begins when Ricky Watson starts confiding in her. He's cute, funny, a good listener—and everything she'd ever want—except that he was killed nearly a year ago. Krystal's ghost-whispering talents soon lead other "freaks" to her door—Sasha, a rich girl who can literally disappear, and Jake, who moves objects with his mind. All three share a distinctive birthmark in the shape of an M and, fittingly, call themselves the Mystyx. They set out to learn what really happened to Ricky, only to realize that they aren't the only ones with mysterious powers. But if Krystal succeeds in finding out the truth about Ricky's death, will she lose him for good?
