Chapter Four: Heat Signature

The hospital lights flickered again, a momentary stutter in the oppressive fluorescent glow. Just once. But Isla noticed.

She stood outside Ember’s room, arms folded tightly across her chest, her breath hitching as she watched the monitors through the glass. The rhythmic beeping had become a somber soundtrack of hope and uncertainty. The girl inside hadn’t moved an inch, but something in the air felt… alive. Like the room itself was holding its breath, waiting for the inevitable moment of awakening.

Kael returned quietly, his boots making barely a sound on the sterile linoleum. Isla turned toward him, startled by how desperately close he had come without her realising. Again.

“You’re watching her,” he said, his voice low and steady.

“She’s changing,” Isla replied, her brows furrowing as she glanced back at Ember. “And I think you knew she would.” The accusation hung thick between them, filled with the weight of secrets yet to be unveiled.

Kael didn’t answer immediately, his eyes glued to Ember, but Isla felt the weight of his attention shift subtly—like he was both seeing her and trying desperately not to. She sensed it in the way his jaw clenched and the way his fingers curled into fists at his sides, as if resisting an unspoken urge.

“You said she’s the key,” Isla pressed, taking a cautious step closer, her heart racing. “To what?”

Kael hesitated, and when he finally spoke, his voice dropped even lower. “To everything.”

Isla stepped closer still, her pulse quickening. “That’s not an answer.”

Kael’s gaze flickered to her lips for the briefest moment, a silent weight stirring in the space between them. Then he looked away, as if the heat that simmered between them was something too dangerous to acknowledge.

“She’s waking up,” he said, voice steady, but his expression was grave. “And when she does, the people who want her won’t knock. They’ll burn through the walls.”

Isla’s heart raced. “And you think I can protect her?”

“I think you already are,” he replied, his eyes intense.

She didn’t know how to respond to that. The silence thickened between them, a tangle of thoughts and emotions neither dared to voice.

Kael’s eyes returned to her face—taking in the copper strands of her hair pulled back into a loose ponytail, though he imagined it cascading in wild waves down her back, damp with sweat or tangled from sleep. Her skin was pale, dotted with freckles, and glowed faintly in the emergency lighting, making her look almost ethereal. But it wasn’t just the light—it was her. The way she stood, the way she held herself. Like she didn’t belong to the surrounding chaos, but refused to be untouched by it.

Her green eyes were filled with questions, but behind that confusion lay something deeper. Something that ignited a flicker of yearning in him—a hunger to answer not just her questions, but the unspoken ones he’d buried so deep he barely recognised them anymore.

She was beautiful. Undeniably so. Sweet-looking, yes—but not soft. Not with the steel he sensed in her spine. He felt it every time she challenged him, every time she held his gaze without flinching. It thrilled him. It terrified him. It made him want to see what she looked like when she let go.

He wanted to reach out, to touch her—not just her hand, not just her cheek, but the curve of her waist, the line of her throat, the heat of her skin beneath his palms. He wanted to kiss her until the world outside those walls disappeared. Until the war, the wards, the weight of duty dissolved into nothing but breath and skin and need.

He wanted to remember what it felt like to want something just for himself. To crave. To take. To be taken.

And in that moment, with the lights flickering, and her eyes locked on his, he wondered what she’d do if he closed the distance. If he let instinct win.

If he let himself want her out loud.

But he didn’t move.

“I dreamed of you,” he said quietly, vulnerability threading through his voice.

Isla blinked, momentarily taken aback. “What?”

Kael shook his head, dismissing the weight of the admission as if it were trivial. “Doesn’t matter.”

But it did. Isla felt it blossom in her chest, a flicker of warmth that chased away panic. She stepped back, needing space, needing air, trying to process the implications of his words. “I should check Ember’s vitals,” she said, her voice steadier than she felt.

Kael nodded. “I’ll stay close,” he offered, an unspoken promise forming in the air between them.

As Isla turned back toward the room, the heat returned—not from Ember, but from Kael. It radiated from the space between them, charged with an unacknowledged truth neither of them was ready to confront.
