Sierra arrives at the Tower with Nydia, disturbed that Wick has been hiding there the whole time, and “was probably up there now, watching her every move” (254). Even though Sierra sent her friends a text warning them to stay away, Bennie, Tee, and Juan show up prepared to help her fight. The lights cut out as they enter the Tower. Sierra suggests splitting up, but Bennie argues they are stronger together. The lights come back on, and Juan thinks he hears a noise like a muffled moan. They climb the stairs of the tower and corpuscules attack them. Sierra discovers she can re-kill the corpuscules by pushing through their eyes, releasing the spirit from the body. Juan realizes he knew one of the corpuscules when he was still alive and feels guilt that he killed him. The friends regroup, and Sierra worries about what else lies in store for them.

Sierra and her friends continue into the Tower, when Sierra feels overwhelmed by a thickening in the air, “the ferocious swell of a wave before it breaks” (263).
