I rose from the couch, clenched my hands into fists, and forced myself to look Incitatus in the eye.

“I’m still the god Apollo,” I warned. “I’ve faced two emperors already. I beat them both. Don’t test me, horse.”

Incitatus snorted. “Whatever, Lester. You’re getting weaker. We’ve been keeping an eye on you. You’ve got hardly anything left. Now quit stalling.”

“And how will you force me to come with you?” I demanded. “You can’t pick me up and throw me on your back. You have no hands! No opposable thumbs! That was your fatal mistake!”

“Yeah, well, I could just kick you in the face. Or…” Incitatus nickered—a sound like someone calling their dog.

Wah-Wah and two of his guards slunk into the room. “You called, Lord Stallion?”

The horse grinned at me. “I don’t need opposable thumbs when I’ve got servants. Granted, they’re lame servants that I had to chew free from their own zip ties—”

“Lord Stallion,” Wah-Wah protested. “It was the ukulele! We couldn’t—”

“Load ’em up,” Incitatus ordered, “before you put me in a bad mood.”

Wah-Wah and his helpers threw Piper across the horse’s back. They forced me to climb up behind her, then they bound my hands once again—this time in front, at least, so I could better keep my balance.

Finally, they pulled Crest to his feet. They wrangled the physically abusive winged shoes back into their box, zip-tied Crest’s hands, and force-marched him in front of our grim little parade. We made our way up to the deck, me ducking under every lintel, and retraced our path across the floating bridge of super-yachts.

Incitatus trotted along at an easy pace. Whenever we passed mercenaries or crew members, they knelt and lowered their heads. I wanted to believe they were honoring me, but I suspected they were honoring the horse’s ability to bash their heads in if they didn’t show proper respect.

Crest stumbled. The other pandai hauled him to his feet and prodded him along. Piper kept slipping off the stallion’s back, but I did my best to keep her in place.

Once she muttered, “Uhn-fu.”

Which might have meant Thank you or Untie me or Why does my mouth taste like a horseshoe?

Her dagger, Katoptris, was in easy reach. I stared at the hilt, wondering if I could draw it quickly enough to cut myself free, or plunge it into the horse’s neck.

“I wouldn’t,” Incitatus said.

I stiffened. “What?”

“Use the knife. That’d be a bad move.”

“Are—are you a mind-reader?”

The horse scoffed. “I don’t need to read minds. You know how much you can tell from somebody’s body language when they’re riding your back?”

“I—I can’t say that I’ve had the experience.”

“Well, I could tell what you were planning. So don’t. I’d have to throw you off. Then you and your girlfriend would probably crack your heads and die—”

“She’s not my girlfriend!”

“—and Big C would be annoyed. He wants you to die in a certain way.”

“Ah.” My stomach felt as bruised as my ribs. I wondered if there was a special term for motion sickness while riding a horse on a boat. “So, when you said Caligula would eat me for breakfast—”

“Oh, I didn’t mean that literally.”

“Thank the gods.”

“I meant the sorceress Medea will put you in chains and flay your human form to extract whatever remains of your godly essence. Then Caligula will consume your essence—yours and Helios’s both—and make himself the new god of the sun.”

“Oh.” I felt faint. I assumed I still had some godly essence inside me—some tiny spark of my former awesomeness that allowed me to remember who I was and what I had once been capable of. I didn’t want those last vestiges of divinity taken away, especially if the process involved flaying. The idea made my stomach churn. I hoped Piper wouldn’t mind terribly if I threw up on her. “You—you seem like a reasonable horse, Incitatus. Why are you helping someone as volatile and treacherous as Caligula?”

Incitatus whinnied. “Volatile, schmolatile. The boy listens to me. He needs me. Doesn’t matter how violent or unpredictable he may seem to others. I can keep him under control, use him to push through my agenda. I’m backing the right horse.”

He didn’t seem to recognize the irony of a horse backing the right horse. Also, I was surprised to hear that Incitatus had an agenda. Most equine agendas were fairly straight-forward: food, running, more food, a good brushing. Repeat as desired.

“Does Caligula know that you’re, ah, using him?”

“Of course!” said the horse. “Kid’s not stupid. Once he gets what he wants, well…then we part ways. I intend to overthrow the human race and institute a government by the horses, for the horses.”

“You…what?”

“You think equine self-governance is any crazier than a world ruled by the Olympian gods?”

“I never thought about it.”

“You wouldn’t, would you? You, with your bipedal arrogance! You don’t spend your life with humans constantly expecting to ride you or have you pull their carts. Ah, I’m wasting my breath. You won’t be around long enough to see the revolution.”

Oh, reader, I can’t express to you my terror—not at the idea of a horse revolution, but at the thought that my life was about to end! Yes, I know mortals face death, too, but it’s worse for a god, I tell you! I’d spent millennia knowing I was immune to the great cycle of life and death. Then suddenly I find out—LOL, not so much! I was going to be flayed and consumed by a man who took his cues from a militant talking horse!

As we progressed down the chain of super-yachts, we saw more and more signs of recent battle. Boat twenty looked like it had been struck repeatedly with lightning. Its superstructure was a charred, smoking ruin, the blackened upper decks spackled with fire-extinguisher foam.

Boat eighteen had been converted into a triage center. The wounded were sprawled everywhere, groaning from bashed heads, broken limbs, bleeding noses, and bruised groins. Many of their injuries were at knee level or below—just where Meg McCaffrey liked to kick. A flock of strixes wheeled overhead, screeching hungrily. Perhaps they were just on guard duty, but I got the feeling they were waiting to see which of the wounded did not pull through.

Boat fourteen was Meg McCaffrey’s coup de grace. Boston ivy had engulfed the entire yacht, including most of the crew, who were stitched to the walls by a thick web of crawlers. A cadre of horticulturists—no doubt called up from the botanical gardens on boat sixteen—were now trying to free their comrades using clippers and weed-whackers.

I was heartened to see that our friends had made it this far and caused so much damage. Perhaps Crest had been mistaken about them being captured. Surely two capable demigods like Jason and Meg would have managed to escape if they got cornered. I was counting on it, since I now needed them to rescue me.

But what if they could not? I racked my brain for clever ideas and devious schemes. Rather than racing, my mind moved at a wheezing jog.
