Artemis Fowl and the Atlantis Complex by Eoin Colfer

one knows, they all know.”
    Holly scanned Artemis’s vitals through her visor. The glowing readouts informed her that he had a slight heart murmur and there was some unusual brain activity in the parietal lobe. Other than that, the best thing her helmet computer could conclude about Artemis was that he was basically not dead. If she could survive this latest misadventure, maybe Artemis would too.
    “What are they looking for, Foaly?”
    “What are they looking for?” repeated the centaur, smiling that particular hysterical smile that exposed too much gum.
    Holly suddenly felt her senses snap into focus and knew that the magic had finished its overhaul of her injuries. Her pelvis still throbbed and probably would for a few months, but she was operational again, so maybe she could lead them back to fairy civilization.
    “Foaly, pull yourself together. We need to know what those things can do.”
    The centaur seemed put out that someone would choose this particular moment to ask him questions when he had so many vital issues to consider.
    “Holly, really! Do we have time for explanations now?”
    “Snap out of it, Foaly! Information, hand it over.”
    Foaly sighed, lips flapping. “They are biospheres. Amorphobots. Dumb plasma-based machines. They collect samples of plant life and analyze them in their plasma. Simple as that. Harmless.”
    “Harmless,” blurted Holly. “I think someone has reprogrammed your amorphobots, centaur.”
    The blood disappeared from Foaly’s cheeks and his fingers twitched. “No. Not possible. That probe is supposed to be on its way to Mars to search for microorganisms.”
    “I think we can be pretty sure that your probe has been hijacked.”
    “There is another possibility,” suggested Foaly. “I could be dreaming all of this.”
    Holly pressed on with her questions. “How do we stop them, Foaly?”
    It was impossible to miss the fear that flickered across Foaly’s face, like a sun flash across a lake. “Stop them? The amorphobots are built to withstand prolonged exposure to open space. You could drop one of these onto the surface of a star and it would survive for long enough to transmit some information back to its mother probe. Obviously I have a kill code, but I suspect that has been overridden.”
    “There must be a way. Can’t we shoot them?”
    “Absolutely not. They love energy. It feeds their cells. If you shoot them, they’ll just get bigger and more powerful.”
    Holly laid a palm on Artemis’s forehead, checking his temperature.
    I wish you would wake up, she thought. We could really use one of your brilliant schemes right now .
    “Foaly,” she said urgently. “What are the amorphobots doing right now? What are they looking for?”
    “Life,” replied Foaly simply. “They’re doing a grid search now, starting at the drop site and moving out. Any life forms they encounter will be absorbed into the sac, analyzed, then released.”
    Holly peeped over the lip of the crater. “What are their scan criteria?”
    “Thermal is the default. But they can use anything.”
    Thermal, thought Holly. Heat signatures. That’s why they are spending so much time by the flaming shuttle.
    The amorphobots were arranged on corners of invisible grid squares, slowly working their way outward from the shuttle’s smoking carcass. They seemed innocuous enough, rolling balls of gel with twin glowing red sensors at their cores. Like slime balloons from a children’s party.
    Maybe the size of a crunchball.
    They couldn’t be all that dangerous surely. Dozy little blebers.
    Her opinion altered sharply when one of the amorphobots changed color from translucent green to angry electric blue and the color spread to the others. Their eerie chittering became a constant shrill whine.
    They have found something, Holly realized.
    The entire squad of twenty or so bots converged on a single spot, some merging so that they formed larger blobs, which flowed across the ice with a speed and grace
