A shower of sparks suddenly flared to life on the floppy-screen display, highlighting Wheeler’s face in vivid chartreuse. Archangel nearly dropped the latest box she was working on. Taking one hand from the box, she closed her hand into a fist, then opened it again a moment later to reveal a blue-white gem as large as the ball of her thumb. She tossed the gem away into a corner of the black and green room. The chartreuse sparks immediately leapt after it, freeing her to work on the box.
