Back at the Academy, sleep was something that Rose never seemed to manage to get enough of. Between the early morning training sessions with Dimitri and being dragged in to Lissa's late night rendezvous with Christian through the bond, she spent most of her time in an almost sleep deprived state. Once the bond dissolved, she thought she might actually develop a somewhat normal sleep schedule, and she was right—for a while. Completely content, she falls asleep wrapped in the strong arms of her Russian god, feeling safe and secure. Even on the nights when Dimitri's reoccurring nightmares wake them, she has no complaints—she simply cuddles up close to him and whispers soft, reassuring things until they both drift back to sleep.
It's the nights when Dimitri has a late patrol or has to work a double shift that torment her. Those are the nights when she can't sleep, haunted by the image of him falling in the cave. She tosses and turns for hours, fighting back the urge to call and check up on him, telling herself that she's overreacting. When he finally comes home and crawls into their bed, pulling her close to his broad chest, she clings to him with relief. Snuggled up against him and listening to the sound of his heart beating, she is able to relax and close her eyes.
Only then can she finally fall asleep, but before she does, she always remembers to say a silent thank you—to whoever might be listening—for bringing him home to her, safe and sound.
