The Sea of Monsters

wanted a second look. I guess it isn’t every day they see a yellow lifeboat with no engine going a hundred knots an hour, manned by three kids.
    “That’s Virginia Beach!” Annabeth said as we approached the shoreline. “Oh my gods, how did the Princess Andromeda travel so far overnight? That’s like—”
    “Five hundred and thirty nautical miles,” I said.
    She stared at me. “How did you know that?”
    “I—I’m not sure.”
    Annabeth thought for a moment. “Percy, what’s our position?”
    “36 degrees, 44 minutes north, 76 degrees, 2 minutes west,” I said immediately. Then I shook my head. “Whoa. How did I know that?”
    “Because of your dad,” Annabeth guessed. “When you’re at sea, you have perfect bearings. That is so cool.”
    I wasn’t sure about that. I didn’t want to be a human GPS unit. But before I could say anything, Tyson tapped my shoulder. “Other boat is coming.”
    I looked back. The coast guard vessel was definitely on our tail now. Its lights were flashing and it was gaining speed.
    “We can’t let them catch us,” I said. “They’ll ask too many questions.”
    “Keep going into Chesapeake Bay,” Annabeth said. “I know a place we can hide.”
    I didn’t ask what she meant, or how she knew the area so well. I risked loosening the thermos cap a little more, and a fresh burst of wind sent us rocketing around the northern tip of Virginia Beach into Chesapeake Bay. The coast guard boat fell farther and farther behind. We didn’t slow down until the shores of the bay narrowed on either side, and I realized we’d entered the mouth of a river.
    I could feel the change from salt water to fresh water. Suddenly I was tired and frazzled, like I was coming down off a sugar high. I didn’t know where I was anymore, or which way to steer the boat. It was a good thing Annabeth was directing me.
    “There,” she said. “Past that sandbar.”
    We veered into a swampy area choked with marsh grass.
    I beached the lifeboat at the foot of a giant cypress.
    Vine-covered trees loomed above us. Insects chirred in the woods. The air was muggy and hot, and steam curled off the river. Basically, it wasn’t Manhattan, and I didn’t like it.
    “Come on,” Annabeth said. “It’s just down the bank.”
    “What is?” I asked.
    “Just follow.” She grabbed a duffel bag. “And we’d better cover the boat. We don’t want to draw attention.”
    After burying the lifeboat with branches, Tyson and I followed Annabeth along the shore, our feet sinking in red mud. A snake slithered past my shoe and disappeared into the grass.
    “Not a good place,” Tyson said. He swatted the mosquitoes that were forming a buffet line on his arm.
    After another few minutes, Annabeth said, “Here.”
    All I saw was a patch of brambles. Then Annabeth moved aside a woven circle of branches, like a door, and I realized I was looking into a camouflaged shelter.
    The inside was big enough for three, even with Tyson being the third. The walls were woven from plant material, like a Native American hut, but they looked pretty waterproof. Stacked in the corner was everything you could want for a campout—sleeping bags, blankets, an ice chest, and a kerosene lamp. There were demigod provisions, too— bronze javelin tips, a quiver full of arrows, an extra sword, and a box of ambrosia. The place smelled musty, like it had been vacant for a long time.
    “A half-blood hideout.” I looked at Annabeth in awe. “You made this place?”
    “Thalia and I,” she said quietly. “And Luke.”
    That shouldn’t have bothered me. I mean, I knew Thalia and Luke had taken care of Annabeth when she was little. I knew the three of them had been runaways together, hiding from monsters, surviving on their own before Grover found them and tried to get them to Half-Blood Hill. But whenever Annabeth talked about the time she’d spent with them, I kind of felt . . . I don’t know. Uncomfortable?
    No. That’s not the word.
    The word was jealous .
    “So . . .” I said. “You don’t think Luke will look for us here?”
    She shook her head. “We made a dozen safe houses like this. I doubt Luke even remembers where they are. Or cares.”
    She threw herself down on the blankets and started going through her duffel bag. Her body language made it pretty clear she didn’t want to talk.
    “Um, Tyson?” I said. “Would you mind scouting around outside? Like, look for a wilderness convenience store or
