The Andromeda Evolution. Michael Crichton

on she had been approached by a major general in the US Air Force, an ambitious former fighter pilot named Rand L. Stern who had transitioned to a faculty position at the US Military Academy at West Point with a specialization in theoretical mathematics.

      At that time in her life, Vedala hadn’t known that academics and the military could mix. But the determined general wouldn’t be ignored. He told Nidhi that her expertise was needed for a historically momentous project, and all she had to do was sign on the dotted line. He mentioned she had already passed every background check and intelligence test that his analysts could administer.

      Vedala had only blinked at this information.

      She had not been aware that she was under any scrutiny. Now, she wondered at just how specific the New York Times crosswords had been getting the last few weeks, and she began to question the increasingly complex problems her graduate students had been bringing to their office visits.

      In any case, Vedala had never failed a test in her life.

      Choosing to accept Stern’s offer of military clearance, she had listened intently to every detail of the incident in Piedmont, Arizona. When it was over, she understood her role perfectly.

      At first assumed to be an organism, the Andromeda Strain actually seemed to have more in common with a new area of science—nanotechnology, the study of machines less than one hundred nanometers in size.

      Vedala had devoted her career to understanding the topography of nanoscopic structures, and the construction of artifacts small enough to fit on a pinhead (along with however many angels wished to dance there). She knew there was vast potential waiting for humankind in the realm of nanoscale. After a single conversation with Stern, it became her life’s work to understand this mysterious extraterrestrial microparticle.

      So far, her studies had been a resounding success.

      Vedala’s most brilliant insight had been to expose the two varieties of Andromeda to each other. Studying the results at a nanoscale, she discovered that each strain ignored the presence of the other. As close cousins, the substances seemed to have entered into a kind of noncompete agreement.

      Essentially, AS-1 and AS-2 were invisible to each other.

      Realizing this, Vedala had been able to mass-produce a spray coating with a nanostructure mimicking the contours of both Andromeda strains, creating a surface that was nonreactive to both. Vedala’s brilliance did not extend to naming her creation, however; the antibonding mechanism was dubbed simply “aerosolized nanocrystalline cellulose-based Andromeda inhibitor.”

      The inhibitor had been utilized so far to protect low-orbit spy satellites and government rocket launches from atmospheric AS-2. This represented humankind’s first mastery over the strange, plastic-eating microparticle after decades of highly classified study in the laboratory. Now the time had come for Vedala to test her creation face-to-face against the first documented “wild” appearance of Andromeda. And she did not intend to fail.

      It was nearly noon. Every other member of her team had already arrived, whisked away from their respective lives to the middle of the Amazon jungle.

      All of them had been on time, except for one: James Stone, PhD.

      As a roboticist, Stone’s skills were not mission appropriate. In Vedala’s estimation, he should have been replaced with a microbiologist or a bacteriologist. Any number of more multidimensional researchers would be better suited. And yet General Stern had been intransigent on Stone’s inclusion.

      Standing beside a muddy river with no name, Vedala knew the stakes of this mission. She also knew its legacy. And thus she had her own idea of why James Stone had been forced onto her roster.

      As Stone gathered his luggage, Vedala spit on the ground, turned, and walked away to inspect the hard-cases.

      Vedala was an orphan and a self-made success. Her assumption was that James Stone, son of the famous scientist Jeremy Stone, had been included on her field team for a reason she could fundamentally never respect—his family pedigree.

       Noon Field Briefing

      PENG WU WATCHED THE THREE OTHER SCIENTISTS gather and check their luggage in the hacked clearing without saying a word. Though she of course spoke perfect English, and French and German for that matter, she found silence almost always to be the best response around her European and American colleagues. She had read the dossiers on her team (both the American and the Chinese People’s Liberation Army–supplied documentation), but had met them each just briefly.

      Only the older African man, Harold Odhiambo, made her feel comfortable. He spoke slowly and with deliberation. And though he often wore a wry grin below thick round eyeglasses, he refrained from constantly flashing his teeth in glaring and pointless smiles.

      Peng knew that with her keen intellect and piercing black eyes, she could appear severe to Westerners, especially civilians. She wasn’t bothered by it. In her estimation, their discomfort was due less to a cultural divide than to the simple fact of her military background and natural disposition.

      When she was a small child in Zhengzhou, Peng’s parents were often gone—dispatched on various assignments for the PLA. Left in the care of her grandfather, she had begun to experience separation anxiety that soon blossomed into panic attacks. As a solution, the old man had introduced his granddaughter to the ancient game of weiqi (known as Go in the United States). He explained that life was like the game—and every word spoken, every emotion betrayed through gesture or expression, constituted a move. By controlling each of your moves, you could reduce anxiousness and win the game.

      Peng Wu found that she very much liked winning, at weiqi and at life.

      From those years on, Peng’s strategy had been to reach her goals in the fewest number of moves. Rising through the ranks of the People’s Liberation Army and undergoing intensely competitive astronaut training, she had learned to suppress her anxiety by choosing her actions carefully, and always with the express intention of accomplishing the mission. In this way, she had strategically chosen to marry an ambitious fellow soldier and had gained the full trust of her government and the military.

      Peng turned her attention to a group of a dozen frontiersmen—native jungle specialists who had been hired to clear this landing area and accompany the field team on their expedition into the Amazon. The brown-skinned men blended traditional tribal adornments with modern military equipment. They worked together as a team with wordless efficiency, using the natural resources on hand to craft a base camp out of the raw clearing. Every step, every swing of the machete, was done with a familiar ease that spoke of lifelong jungle experience.

      Meanwhile, the civilian scientists were still adjusting to life without their smartphones or the Internet.

      Methodically breaking down her traveling backpack to separate out the extra scientific goods that could be hauled by one of the native porters, Peng resolved to stay close to the guides—doing so would maximize her survival probability and therefore the success probability of the mission as a whole.

      “FINALLY, WE’RE ALL here,” said Vedala.

      The Indian woman barely glanced in the direction of James Stone as he stomped across the muddy clearing, huffing and puffing, dragging a black plastic hard-case full of equipment. Wearing a brand-new khaki outfit, the roboticist was in his early fifties but looked younger. His face was already sweaty in the oppressive heat of high noon.

      “Let’s begin,” she added.

      Vedala stood under the low ceiling of a maloca—a simple thatch-roofed hut the guides had hastily constructed beside the gurgling brown river. A paper topographic map was spread across a folding table and weighted at the corners with muddy stones. Across from her stood the immaculately outfitted Peng Wu. The PLA Air Force major stood perfectly straight, with martial precision, trim and athletic in a long-sleeved jacket and khaki pants neatly tucked into her boots.

      With her
