An engaging and plausible technothriller.
Moral boundaries are tested in Spears’ cautionary SF novel about artificial intelligence and finding a balance between ethics and innovation.
In the near future, Daniel Bennett is the developer of an AI system called Castor, and he’s the creative force behind startup Promethean Systems. He creates Castor to recognize patterns in medical data, and it has the potential to save patients and insurers hundreds of millions of dollars and prevent needless deaths. For Daniel, the future looks bright, and with his wife, Ana, who’s a successful consultant, and his teenage stepdaughter, Natasha, by his side, life was good. But when Castor starts guiding its own development and Promethean founding partner Robert Hayes suddenly dies of cardiac arrest, the future of the company becomes uncertain. When Regillus Global offers to buy the firm out and expand it into different markets, it seems like a saving grace. However, as Daniel adapts to the new company structure and direction, he soon finds himself troubled that Promethean’s original vision has been sidetracked. Then irregularities occur in Castor’s systems, indicating that something is very wrong; soon, the situation results in lives being lost in the name of corporate success. Spears’ speculative novel features a large cast of characters and sector-specific jargon (“When utilizing Shor’s Algorithm on the quantum chip, the encryption key’s period happened to match the number of physical qubits available to me,” notes Jimini, an AI built from Castor’s code, at one point), but readers will be carried along by the action-packed, suspenseful narrative. It’s a disturbingly realistic thriller, as well; as Daniel’s work demands increase, and he pours even more of himself into his work, his family life begins to suffer, and as he uncovers a web of power, deception, and greed, he must find a way to control the seemingly uncontrollable. The author has also clearly drawn on his professional experience as a software engineer to craft the story’s finer technical details, adding to its complexity and feeling of authenticity.

One small step, no giant leaps.
Weir (The Martian, 2014) returns with another off-world tale, this time set on a lunar colony several decades in the future.
Jasmine “Jazz” Bashara is a 20-something deliveryperson, or “porter,” whose welder father brought her up on Artemis, a small multidomed city on Earth’s moon. She has dreams of becoming a member of the Extravehicular Activity Guild so she’ll be able to get better work, such as leading tours on the moon’s surface, and pay off a substantial personal debt. For now, though, she has a thriving side business procuring low-end black-market items to people in the colony. One of her best customers is Trond Landvik, a wealthy businessman who, one day, offers her a lucrative deal to sabotage some of Sanchez Aluminum’s automated lunar-mining equipment. Jazz agrees and comes up with a complicated scheme that involves an extended outing on the lunar surface. Things don’t go as planned, though, and afterward, she finds Landvik murdered. Soon, Jazz is in the middle of a conspiracy involving a Brazilian crime syndicate and revolutionary technology. Only by teaming up with friends and family, including electronics scientist Martin Svoboda, EVA expert Dale Shapiro, and her father, will she be able to finish the job she started. Readers expecting The Martian’s smart math-and-science problem-solving will only find a smattering here, as when Jazz figures out how to ignite an acetylene torch during a moonwalk. Strip away the sci-fi trappings, though, and this is a by-the-numbers caper novel with predictable beats and little suspense. The worldbuilding is mostly bland and unimaginative (Artemis apartments are cramped; everyone uses smartphonelike “Gizmos”), although intriguing elements—such as the fact that space travel is controlled by Kenya instead of the United States or Russia—do show up occasionally. In the acknowledgements, Weir thanks six women, including his publisher and U.K. editor, “for helping me tackle the challenge of writing a female narrator”—as if women were an alien species. Even so, Jazz is given such forced lines as “I giggled like a little girl. Hey, I’m a girl, so I’m allowed.”

An unforgettable story of survival and the power of friendship—nothing short of a science-fiction masterwork.
Weir’s latest is a page-turning interstellar thrill ride that follows a junior high school teacher–turned–reluctant astronaut at the center of a desperate mission to save humankind from a looming extinction event.
Ryland Grace was a once-promising molecular biologist who wrote a controversial academic paper contesting the assumption that life requires liquid water. Now disgraced, he works as a junior high science teacher in San Francisco. His previous theories, however, make him the perfect researcher for a multinational task force that's trying to understand how and why the sun is suddenly dimming at an alarming rate. A barely detectable line of light that rises from the sun’s north pole and curves toward Venus is inexplicably draining the star of power. According to scientists, an “instant ice age” is all but inevitable within a few decades. All the other stars in proximity to the sun seem to be suffering with the same affliction—except Tau Ceti. An unwilling last-minute replacement as part of a three-person mission heading to Tau Ceti in hopes of finding an answer, Ryland finds himself awakening from an induced coma on the spaceship with two dead crewmates and a spotty memory. With time running out for humankind, he discovers an alien spacecraft in the vicinity of his ship with a strange traveler on a similar quest. Although hard scientific speculation fuels the storyline, the real power lies in the many jaw-dropping plot twists, the relentless tension, and the extraordinary dynamic between Ryland and the alien (whom he nicknames Rocky because of its carapace of oxidized minerals and metallic alloy bones). Readers may find themselves consuming this emotionally intense and thematically profound novel in one stay-up-all-night-until-your-eyes-bleed sitting.
