How does Joan Lowery Nixon use imagery in The Other Side of Dark?

Imagery:

"I gasp as my hands feel breasts that are rounded and firm. My shaking fingers slide past my waist, exploring, as the horror grows. I lift my head to look down, down at toes that lump the blanket near the foot of the bed, and the horror explodes in a scream. I am Stacy McAdams. I'm only thirteen years old, and I'm in the wrong body" (Chapter 1, p. 2).

"Jarrod Tucker is second from the right, and I want you to look at his eyes. Four years ago those awful yellow cat eyes stared into mine just before Jarrod shot me. I'll never forget his eyes! Never" (Chapter 11, p. 140).
