According to the Night Watch’s crime blotters, this spot didn’t show any of the usual signs of a predator. No transit workers gone missing, no homeless people turning psychotically violent. But every time New Jersey Pest Control did another round of poisoning, the hordes of rats just reappeared, despite the fact that there wasn’t much garbage to eat in this deserted part of town. The only explanation was a resident peep. When the Night Watch had tested one of the rats, it had turned out to be of my bloodline, once removed.

That could only mean Sarah. Except for her and Morgan, every other girl I’d ever kissed was already locked up tight. (And Morgan, I was certain, was not hiding out in an old ferry terminal in Hoboken.)

Big yellow stickers plastered the terminal’s padlocked doors, warning of rat poison, but it looked like the guys at pest control were starting to get spooked. They’d dropped off their little packets of death, slapped up a few warning stickers, and then gotten the heck out of there.

Good for them. They don’t get paid enough to deal with peeps.

Of course, neither do I, despite the excellent health benefits. But I had a certain responsibility here. Sarah wasn’t just the first of my bloodline—she was my first real girlfriend.

My only real girlfriend, if you must know.

We met the opening day of classes—freshman year, Philosophy 101—and soon found ourselves in a big argument about free will and predetermination. The discussion spilled out of class, into a café, and all the way back to her room that night. Sarah was very into free will. I was very into Sarah.

The argument went on that whole semester. As a bio major, I figured “free will” meant chemicals in your brain telling you what to do, the molecules bouncing around in a way that felt like choosing but was actually the dance of little gears—neurons and hormones bubbling up into decisions like clockwork. You don’t use your body; it uses you.
