It was a tragic accident...right? After Macy's brother dies over the summer, she doesn't expect the first day of her junior year to feel normal. But when she starts seeing things - including a teacher bursting into flames - she begins to question her own sanity. Now, she sees signs of the dead everywhere, and she and a group of new friends may be all that stands between the new high school and a doorway to hell.
