Eliza glares at him in envy. Last night had been a restless one, and it wasn't like she'd been able to sleep on the helicopter. In that moment, she would have given almost anything for the ability to fall asleep on a dime.... I wonder if there's a gem that has to do with sleep. Maybe something that would let her steal sleep from other people, like a vampire?
Another wave of sleepiness rolls over her, and she plops on the ground with a yawn. As dumb as it sounded, being a sleep vampire could be pretty nice.
