It syncs with the pulsing in his wrists, a circulation pattern he doesn’t remember ever having. He stops. The vibration stops with him. “Riven?” Lyra’s voice floats in from the living room. Worried. Lightweight. Practiced calm. “You okay?” He tries to answer, but something shifts again. A half-second
