The Sea of Monsters

the center of the vortex.
    A zombie sailor burst out of the hold and ran to Clarisse. His gray uniform was smoking. His beard was on fire. “Boiler room overheating, ma’am! She’s going to blow!”
    “Well, get down there and fix it!”
    “Can’t!” the sailor yelled. “We’re vaporizing in the heat.”
    Clarisse pounded the side of the casemate. “All I need is a few more minutes! Just enough to get in range!”
    “We’re going in too fast,” the captain said grimly. “Prepare yourself for death.”
    “No!” Tyson bellowed. “I can fix it.”
    Clarisse looked at him incredulously. “You?”
    “He’s a Cyclops,” Annabeth said. “He’s immune to fire. And he knows mechanics.”
    “Go!” yelled Clarisse.
    “Tyson, no!” I grabbed his arm. “It’s too dangerous!”
    He patted my hand. “Only way, brother.” His expression was determined—confident, even. I’d never seen him look like this before. “I will fix it. Be right back.”
    As I watched him follow the smoldering sailor down the hatch, I had a terrible feeling. I wanted to run after him, but the ship lurched again—and then I saw Charybdis.
    She appeared only a few hundred yards away, through a swirl of mist and smoke and water. The first thing I noticed was the reef—a black crag of coral with a fig tree clinging to the top, an oddly peaceful thing in the middle of a maelstrom. All around it, water curved into a funnel, like light around a black hole. Then I saw the horrible thing anchored to the reef just below the waterline—an enormous mouth with slimy lips and mossy teeth the size of rowboats. And worse, the teeth had braces, bands of corroded scummy metal with pieces of fish and driftwood and floating garbage stuck between them.
    Charybdis was an orthodontist’s nightmare. She was nothing but a huge black maw with bad teeth alignment and a serious overbite, and she’d done nothing for centuries but eat without brushing after meals. As I watched, the entire sea around her was sucked into the void—sharks, schools of fish, a giant squid. And I realized that in a few seconds, the CSS Birmingham would be next.
    “Lady Clarisse,” the captain shouted. “Starboard and forward guns are in range!”
    “Fire!” Clarisse ordered.
    Three rounds were blasted into the monster’s maw. One blew off the edge of an incisor. Another disappeared into her gullet. The third hit one of Charybdis’s retaining bands and shot back at us, snapping the Ares flag off its pole.
    “Again!” Clarisse ordered. The gunners reloaded, but I knew it was hopeless. We would have to pound the monster a hundred more times to do any real damage, and we didn’t have that long. We were being sucked in too fast.
    Then the vibrations in the deck changed. The hum of the engine got stronger and steadier. The ship shuddered and we started pulling away from the mouth.
    “Tyson did it!” Annabeth said.
    “Wait!” Clarisse said. “We need to stay close!”
    “We’ll die!” I said. “We have to move away.”
    I gripped the rail as the ship fought against the suction. The broken Ares flag raced past us and lodged in Charybdis’s braces. We weren’t making much progress, but at least we were holding our own. Tyson had somehow given us just enough juice to keep the ship from being sucked in.
    Suddenly, the mouth snapped shut. The sea died to absolute calm. Water washed over Charybdis.
    Then, just as quickly as it had closed, the mouth exploded open, spitting out a wall of water, ejecting everything inedible, including our cannonballs, one of which slammed into the side of the CSS Birmingham with a ding like the bell on a carnival game.
    We were thrown backward on a wave that must’ve been forty feet high. I used all of my willpower to keep the ship from capsizing, but we were still spinning out of control, hurtling toward the cliffs on the opposite side of the strait.
    Another smoldering sailor burst out of the hold. He stumbled into Clarisse, almost knocking them both overboard. “The engine is about to blow!”
    “Where’s Tyson?” I demanded.
    “Still down there,” the sailor said. “Holding it together somehow, though I don’t know for how much longer.”
    The captain said, “We have to abandon ship.”
    “No!” Clarisse yelled.
    “We have no choice, m’lady. The hull is already cracking apart! She can’t—”
    He never finished his sentence. Quick as lightning, something brown and green shot from the sky, snatched up the
