Thanks, said George, as I stepped out into the hall.

“No problem,” I murmured, cracking open her soda and taking a long drink before heading toward the door to the roof-access stairs. In most buildings, tromping around on the roof is likely to get you shot. Just another advantage of living where I do: Mrs. Hagar can’t even hear us up there unless we’re setting off land mines, and we’ve done that only once, for quality control purposes.

There used to be a padlock on the door leading to the roof-access stairs. As if the infected were going to be mounting a top-down attack? That stopped happening when the mass outbreaks stopped driving the wounded to the rooftops to wait for rescue that never came. The manager periodically realizes that the lock is missing and replaces it, and someone on my staff comes along and cuts it off the next day. That’s the circle of life around here. Nothing stays locked away forever.

You’re depressing today.

“It’s a depressing sort of day,” I said. George quieted, and I climbed the stairs in something that was chillingly close to solitude.

I don’t deal well with being alone. Maybe that’s why I decided to go crazy instead.

My crew’s been working on converting the roof to suit our needs since we took over the third floor. It’s one of those projects that’s never going to be finished; there’s something new every time I go up there. Dave has what he calls his “outdoor theater,” a little grouping of folding chairs and a collapsible movie screen under a pavilion he bought at the Wal-Mart in Martinez. He brings out a projector on warm nights and shows pre-Rising horror movies. I think he’s trying to lure Maggie out of her house and into the city by competing with her grindhouse parties, and if he keeps it up, he just may succeed.

Becks has a small firing range with targets designed for everything from basic handguns to her personal favorite weapon, the wrist-mounted crossbow. That girl reads too many comic books. Still, I have to say, the sight of a zombie’s head catching fire after it gets hit with one of her trick arrows isn’t something I’m going to forget anytime soon. Neither are our viewers.

And me? I have a corner of the roof where no one does anything else, where I can go and sit and drink a Coke and watch the clouds chase themselves across the sky, and where I don’t have to be the boss for a little while. I can just be me. When I go up there, my staff’ll move heaven and earth to keep anyone from following me, because they know I need the escape. They’ve mostly gotten over treating me like I’m made of eggshells, but there are exceptions.

A pigeon was sitting on the edge of the roof when I walked up, cooing contentedly to itself. It looked at me suspiciously, but waited to see what I would do before going to the trouble of flying away. When I just sat, it resumed its cocky back-and-forth strut without a second thought.

“Must be nice to be a pigeon,” I said, taking another swig of Coke and making a face. “You sure can’t sell you on the idea of coffee? Nice, bitter, hot coffee that doesn’t taste like going down on a hooker from Candyland?”

You never objected to me drinking Coke before, George replied.

“Yeah, George, but you didn’t live inside my head before. You can use this stuff to clean car batteries. Car batteries, George. You think that’s doing anything good to my internal organs? Because I’d bet good money that it’s not.”

Shaun, said George, in that all-too-familiar, all-too-exasperated tone, I don’t live anywhere. I’m not alive. Remember?

“Yeah, George,” I said, taking one last drink from the can of Coke before tossing it, still half full, off the edge of the roof. It sprayed soda in an impressively large arc as it fell. I leaned backward against the building’s air-ventilation shaft and closed my eyes. “I remember.”

As I’ve mentioned several times, I have a sister. An adopted sister, to be precise, fished out of the state system by Michael and Stacy Mason after the Rising left us both without our biological parents. That was George. She’s the reason I got into blogging, and the reason we wound up running a site of our own. She was never meant to be one of nature’s followers. And technically, I guess the tense is wrong there, because it ought to be “I had a sister.” The death of Georgia Carolyn Mason was registered with the Centers for Disease Control on June 20, 2032. Her official cause of death is recorded as “complications from massive amplification of the Kellis-Amberlee virus,” which means, in layman’s terms, “she died because she turned into a zombie.”

It would be a lot more accurate to say that she died because I shot her in the spine, spraying blood all over the interior of the van that we were locked in at the time. It might be even more accurate to say that she died because some bastard shot a needle full of the live Kellis-Amberlee virus into her arm. But the CDC says she died of Kellis-Amberlee, and hey, we don’t argue with the CDC, right?

If I ever find out who fired that needle, their official cause of death is going to be Shaun Mason. That’s the thought that keeps me going. I sleepwalk through my job, I pretend I’m administrating our site while Mahir does all the work, I delete calls from my crazy parents, I hold conversations with my dead sister, and I look for the people who had her killed. I’ll find them someday. All I have to do is wait.

See, when the zombies came, it was an accident. Researchers in two totally unconnected facilities were working on two totally unrelated projects that involved genetically engineering “helper viruses”—new diseases that were supposed to make life better for the whole damn world. One of them was based on a really f**king nasty hemorrhagic fever called Marburg, and was designed to cure cancer. The other was based on a strain of the common cold, and was supposed to get rid of colds forever. Enter Marburg Amberlee and the Kellis Flu, two beautiful pieces of viral engineering that did exactly what they were supposed to do. No more cancer, no more colds, just happy people all over the world celebrating the dawn of a new age. Only it turns out the viruses were just like the people who made them in at least one sense, because when they met, through the natural chain of transmission and infection, it was basically love at first sight. First wn of a love, then comes marriage, then comes the hybrid viral strain known as “Kellis-Amberlee.” It swept the planet before anyone knew what was happening.
