Free Curse of the Mummy's Uncle by J. Scott Savage

Nick realized the teeth were the curved stones he’d seen earlier. “It’s a door,” he said, his voice weak and still a little shaky.
    â€œI told you the entrance might look like a monster,” Angelo said. “Look, it’s pretty cool.” He pushed on one of the teeth in the floor and a stone swung down, blending in with the wall. Angelo pushed the tooth again and shoved the door open, making the grinding sound Nick and Carter had heard earlier.
    â€œCouldn’t you just have said, ‘Look, guys, I found a door’?” Carter asked, lowering his needles. “You had to scare us half to death?”
    Angelo laughed. “Sorry. I shut the door behind me and was trying to figure out how to open it. It’s pretty awesome how the light makes it look like a monster though, isn’t it?” He stepped through the door and shined the light, turning the wall back into a demon.
    â€œYeah, awesome ,” Carter grunted.
    â€œLet’s go down and have a look around before the archaeologists come back,” Angelo said.
    Nick peered down the dark passage. The walls were coated with moss and the floors looked wet and slick. “Are you sure it’s safe? What about those traps you were talking about?”
    Angelo handed him the second flashlight. “The archaeologists went down, and they survived.”
    â€œThat’s what the people with Indiana Jones say, right before they get hit by poison darts,” Carter said.
    Nick stepped through the demon’s mouth, duckinghis head to keep from hitting the stone. “It can’t be too dangerous, can it? I mean, they wouldn’t let families come here on vacation if they could get seriously hurt.”
    â€œSo far, your family is the only one here,” Carter said. “Maybe that should tell you something.” But he followed Angelo when he walked into the tunnel.
    The passage was just as damp and slippery as Nick had imagined. He took small, shuffling steps to keep from falling, and ran one hand along the wall.
    Angelo stopped at a section of wall with a series of holes drilled into it and shined his light excitedly up and down. “Look at this!”
    Carter pushed past Nick to get a look, then shook his head in disgust. “Yeah, these are some totally cool holes . Maybe next we can find a rock. Or some dust.”
    â€œThese aren’t just holes. They’re stars. See how they form constellations?” Angelo pointed his finger from one dot to another. “That’s the Big Dipper, also known as Plough. And that’s Orion.” He handed Nick his flashlight and swabbed a couple of the holes, carefully noting the time and date in his notebook. “It’s important to write down where we took each sample. That way, when we get an alien hit, we will be able to track everywhere they went.”
    Nick glanced the way they’d come, wondering how long it would be before the men came back.
    â€œIs it time?” someone asked.
    â€œTime for what?” Nick said.
    Carter looked up from his knitting. “Dinner?”
    Nick snorted. “What are you talking about? We already had dinner.”
    â€œWhat are you talking about?” Carter asked, clearly irritated. “You asked me what it was time for, and I said dinner. If that’s not it, I give up. What’s it time for?”
    â€œHow should I know? You’re the one who asked.”
    â€œWould you two stop arguing,” Angelo said, tucking the swabs into his testing kit. “You’re going to wake the dead. And there are probably at least a few of them down here.”
    Nick glared at Carter, wondering what the point of the argument had been, but his friend had gone back to work on his serape.
    The three of them continued down the hallway, Angelo taking DNA samples every so often.
    â€œAre you here to free me?” a voice asked.
    Nick spun around, sure Carter was messing with him again, but Carter
