After flicking on the light, Lisa repeated her earlier question. “What’s going on?”

Her mom walked over to a dusty corner of the large room and dragged a couple of boxes away from the wall, then crouched down. “I know both you and I have been feeling like we want to help. To finally do our part in this whole mess. Especially now that my son”—she faltered, choked back the usual cry that had come so often since Master George had sent word that Tick was missing—“is nowhere to be found. I think it’s time we took a little of our own action.”

Lisa nodded, feeling the same swell of emotion, knowing she couldn’t speak without cracking. But she agreed. Agreed wholeheartedly. She wanted to do something. She wanted to act.

Her mom gripped a panel of the unpainted wall, and to Lisa’s surprise it came loose. She lifted out a large square and placed it on the ground. Swirls of dust puffed through the air. In the dark recess behind her, an object glinted.

“You’ve been hiding something down here?” Lisa asked.

“Yes. Though I never, never, never thought I’d have to use it again.” She leaned over and reached into the secret compartment.

“What?” Lisa asked, moving closer to get a better look. “What is it?”

Her mom pulled out a long, golden tube with dials and switches running down its sides, then held it up. “It’s a Barrier Wand, sweetie. It’s gonna help us find my boy.”
