She raised her gun for the coup de grace, except the moment the barrel started to spin the lamassu regained its acuities and bounded out of the way, bouncing off a wall and sailing at her. She rolled to the side and flung herself upright. The greater wraith pawed at where she had been.

Sloan failed to understand at first but soon the idea registered. She aimed at a bubble and fired. As before, at the sound of her gun, the lamassu tried to leap away. But her piercing light hit the bubble and ricocheted into other bubbles, and that light ricocheted, until soon the entire bubble grid lit up with constantly-rebounding pillars of light. Despite the contortions of the lamassu's lithe body, shafts impaled it from all directions at once. The mouthless wraith unleashed a piteous inhuman wail and disintegrated into a shower of grief cubes.
