Opal (The Raven Cycle, #4.5)

by Maggie Stiefvater

She had to content herself with stolen glimpses through cracked doors, slender one-inch views of duvet and sheets piled like thunderheads, Adam and sometimes Ronan pillowed among them.

Sometimes they would stop talking and instead begin kissing, and Opal would eavesdrop on this as well. Her capacity for voyeurism was boundless and incorrigible. They were always coming together in surprising moments, going from easygoing to urgent in the space of a few breaths. She watched them kiss messily in the car in the driveway and she watched them tangle around each other in the laundry room and she watched Adam unbuckle Ronan’s belt and slide his hand against skin.
