chuckled.
âTheyâre not
that
easy to come by, Ben.â Dr. Ames smiled at him. âI appreciate a man whoâs not afraid to question things. But I do like to think we work some magic here. We have a process that can actually
make
healthy brain cells.â
âYeah?â Ben raised his eyebrows.
âYep. With your own DNA. We insert it into something called a retrovirus. You guys know what a virus is, right?â
âLike cold viruses and flu viruses?â I asked. That didnât sound like something that would make us feel better.
âSimilar. Viruses are tiny organisms that infect a host cell and use it to reproduce. Retroviruses get inside a cell and then spread their
own
genetic material.â
âSo . . . if you have a retrovirus full of
my
genetic material . . .â
âYou got it!â Dr. Amesâs eyes lit up, and he nodded. âIn that case, when we introduce that retrovirus to your system, we get new, healthy brain cells, reproducing to give you back what you lost. Pretty awesome, huh?â He turned and started toward the big building that I figured must be the clinic. âNow, letâs continue our tour.â
âHave you guys started that gene therapy yet?â I asked Sarah, who was hopping over cracks in the sidewalk.
She shook her head. âNoâweâre still on Phase Two. But I hope itâs soon. Itâs totally boring here with so few kids.â
âSo, wait . . .â Mom rushed to catch up with Dr. Ames on the sidewalk. âYou have these four, and . . . two others? Only six patients?â
âAt the moment, yes. We have six
guests
.â He pulled open the clinic door and held it for her. âOur numbers vary. We get people home quickly once theyâve recovered.â He pointed down a long white hallway. âCome this way, and Iâll show you the rest of the facilities.â
He stopped at a set of glass doors partway down the hall. âHereâs our cafeteria, where youâll have your meals unless youâre having a rough day and need to eat in your room.â We filed into the big, bright room. Potted plants grew along the windows, and there were four round tables that looked like regular kitchen tables in regular houses.
âWhere do those steps go?â Ben asked, pointing to the staircase in the corner of the room.
âUp to the roof,â Dr. Ames said. âKiller view. You can go up anytime youâd like and check it out.â
âTheyâre allowed on the
roof
?â Mom tipped her head like sheâd heard wrong.
âItâs more of an upstairs deck,â Dr. Ames said. âTotally safe, completely fenced in.â He held his hand up to his waist to show Mom how safe weâd be. âYou want to see it?â
Mom looked at me.
âNot now,â I said. What I really wanted was to finish this tour so I could lie down. I think Dr. Ames could tell I wasstarting to fade because he put an arm around Mom and led her back to the hallway.
âOur MRI and electroencephalography labs are down this way,â Dr. Ames said, gesturing to his right.
âElectro-huh?â I looked down the hallway.
Dr. Ames laughed. âItâs a mouthfulâjust a fancy name for another kind of brain scan. Iâd show you, but those rooms are in use right now and I donât want to interrupt.â He continued down the hallway. âHereâs my office.â He unlocked a door and led us into a bright, open room with a big wooden desk.
âWhat a lovely view,â Mom said, stepping up to one of the windows that looked out over the swimming pool and, beyond that, the docks. I leaned against the desk, and my hand brushed a manila folder; there were a bunch of them, fanned out next to a laptop computer. The folders were labeled ENRIQUEZ, HAYES, JACOBS, MCCAIN, PERKINS, and mine, GRAYSON. Probably full of our medical files from home. A green Post-it note on the
