I decided Meg must be a feral demigod. They were rare but not unheard of. Without any support network, without being discovered by other demigods or taken in for proper training, she had still managed to survive. But her luck would not last. Monsters usually began hunting down and killing young heroes around the time they turned thirteen, when their true powers began to manifest. Meg did not have long. She needed to be brought to Camp Half-Blood as much as I did. She was fortunate to have met me.

(I know that last statement seems obvious. Everyone who meets me is fortunate, but you take my meaning.)

Had I been my usual omniscient self, I could have gleaned Meg’s destiny. I could have looked into her soul and seen all I needed to know about her godly parentage, her powers, her motives and secrets.

Now I was blind to such things. I could only be sure she was a demigod because she had successfully claimed my service. Zeus had affirmed her right with a clap of thunder. I felt the binding upon me like a shroud of tightly wrapped banana peels. Whoever Meg McCaffrey was, however she had happened to find me, our fates were now intertwined.

It was almost as embarrassing as the acne.

We turned east on Eighty-Second Street.

By the time we reached Second Avenue, the neighborhood started to look familiar—rows of apartment buildings, hardware shops, convenience stores, and Indian restaurants. I knew that Percy Jackson lived around here somewhere, but my trips across the sky in the sun chariot had given me something of a Google Earth orientation. I wasn’t used to traveling at street level.

Also, in this mortal form, my flawless memory had become…flawed. Mortal fears and needs clouded my thoughts. I wanted to eat. I wanted to use the restroom. My body hurt. My clothes stank. I felt as if my brain had been stuffed with wet cotton. Honestly, how do you humans stand it?

After a few more blocks, a mixture of sleet and rain began to fall. Meg tried to catch the precipitation on her tongue, which I thought a very ineffective way to get a drink—and of dirty water, no less. I shivered and concentrated on happy thoughts: the Bahamas, the Nine Muses in perfect harmony, the many horrible punishments I would visit on Cade and Mikey when I became a god again.

I still wondered about their boss, and how he had known where I would fall to earth. No mortal could’ve had that knowledge. In fact, the more I thought about it, I didn’t see how even a god (other than myself) could have foreseen the future so accurately. After all, I had been the god of prophecy, master of the Oracle of Delphi, distributor of the highest quality sneak previews of destiny for millennia.

Of course, I had no shortage of enemies. One of the natural consequences of being so awesome is that I attracted envy from all quarters. But I could only think of one adversary who might be able to tell the future. And if he came looking for me in my weakened state…

I tamped down that thought. I had enough to worry about. No point scaring myself to death with what-ifs.

We began searching side streets, checking names on apartment mailboxes and intercom panels. The Upper East Side had a surprising number of Jacksons. I found that annoying.

After several failed attempts, we turned a corner and there—parked under a crape myrtle—sat an older model blue Prius. Its hood bore the unmistakable dents of pegasus hooves. (How was I sure? I know my hoof marks. Also, normal horses do not gallop over Toyotas. Pegasi often do.)

“Aha,” I told Meg. “We’re getting close.”

Half a block down, I recognized the building: a five-story brick row house with rusty air conditioner units sagging from the windows. “Voilà!” I cried.

At the front steps, Meg stopped as if she’d run into an invisible barrier. She stared back toward Second Avenue, her dark eyes turbulent.

“What’s wrong?” I asked.

“Thought I saw them again.”

“Them?” I followed her gaze but saw nothing unusual. “The thugs from the alley?”

“No. Couple of…” She waggled her fingers. “Shiny blobs. Saw them back on Park Avenue.”

My pulse increased from an andante tempo to a lively allegretto. “Shiny blobs? Why didn’t you say anything?”

She tapped the temples of her glasses. “I’ve seen a lot of weird stuff. Told you that. Mostly, things don’t bother me, but…”

“But if they are following us,” I said, “that would be bad.”

I scanned the street again. I saw nothing amiss, but I didn’t doubt Meg had seen shiny blobs. Many spirits could appear that way. My own father, Zeus, once took the form of a shiny blob to woo a mortal woman. (Why the mortal woman found that attractive, I have no idea.)
