Critical Mass (Delta-V II) – Daniel Suarez

In the sequel to Delta-V, James Tighe and his companions are back on Earth, trying to figure out how to save their two friends still stranded on asteroid Ryugu. A relatively simple problem requiring an increasingly complex plan involving bootstrapping a space economy by building a mass driver on the Moon. The mass driver can launch resources extracted from the Lunar regolith at a fraction of the cost of launching them from Earth, enabling construction of a rescue ship. National and corporate interest on Earth try to get in on the economic and geopolitical frontier, while humanity and Earth suffers increasingly acute social and economic issues due to worsening climate change.

While Delta-V is a more straightforward space thriller, the sequel expands the context, posing important questions such as how to prevent space from becoming just another exploited colonisation boundary for the powerful, while most of humanity remain have-nots. The pace is slower, but the payoff ties it all together. The protagonist as something of a naif in context is a nice detail, illustrating how most people live their lives, even lives doing great things, with little understanding of the bigger picture.

Frontier – Patrick Chiles

Humanity’s presence in space is expanding, and with it come geopolitical interests. The United States spaceship Borman is dispatched to assist two billionaire explorers with whom contact has been lost. Meanwhile, a vast conspiracy to disable space assets is unfolding. As the Borman herself runs into trouble, the People’s Republic of China enters the fray.

As in the earlier Farside set in the same universe, Mr. Chiles expands the scope of the story beyond a mere rescue mission into a technothriller set in space. The protagonists are easy to root for, though they fall into stereotypes rather too readily. The Chinese crew members are almost laughable cardboard cutouts. The story is well crafted, with a good pace apart from an excess of expository dialogue in the first half, and the political tensions eminently plausible.

Delta-V (Delta-V I) – Daniel Suarez

Extreme cave diver James Tighe has just returned from an accident-plagued expedition when he is invited to an interview with eccentric billionaire Nathan Joyce. The latter is planning a mining expedition to an asteroid, and is recruiting suitable candidates. A rigorous selection process follows. The expedition is shrouded in secrecy, with layer within layer of intrigue at every step.

The novel is solid near-future science fiction, elevated beyond the pure adventure aspects by an intricate, if somewhat implausible, technothriller foundation. It seems somewhat beyond belief that thousands of people could keep such a large project a secret for so long, especially given the money involved. The space travel aspects are well developed and quite plausible. The inclusion of secondary characters based on NewSpace luminaries such as Musk, Bezos, Branson and Bigelow is rather entertaining and provides a connection to what, in the real world, is shaping up to be a fierce competition for the space economy. The protagonists themselves, unfortunately, are not very well rounded, down to their stereotypical backstories. That being said, they are easy to root for, throughout their tragedies and triumphs.

On to the Asteroid (Space Excursions II) – Travis S. Taylor & Les Johnson

A billionaire industrialist launches an automated mission to an asteroid, aiming to redirect it into a Lunar orbit for future extraction of minerals. The propulsion system malfunctions before completing the redirection maneuver, and now the asteroid is heading for impact with Earth. A desperate repair mission is launched.

The story is excellent. High stakes, interesting technical solutions, lots of hardcore space action, and a high pace. Unfortunately, and just like the previous book, it is let down by atrocious dialogue and cardboard cutout characters. The dialogue is especially cringeworthy. I did enjoy it because despite these negatives, it is a great yarn, but I wouldn’t recommend it unless you’re a real space buff.

Zero Limit – Jeremy K. Brown

Caitlin Taggart is stuck on the Moon, unable to get home to her daughter on Earth, after international tension has led to a travel ban for Moonborn like her. She works as a regolith miner. She is offered an illegal asteroid mining job for a chance to get home. On the job, things go very wrong for Caitlin and her crew, with consequences that threaten Earth itself.

Leaving aside the handwavy physics poorly suited to a hard science fiction story, I found this novel unengaging. Apart from the well developed protagonist, the rest of the characters seem like cardboard cutouts, with actions dictated by “plot reasons”. While the scope of the story is ambitious, and the flashback scenes are well written, the whole thing doesn’t gel.

Farside – Patrick Chiles

In the sequel to Perigee, Polaris Spacelines has started to establish tour service around the Moon. On one such flight, an incident occurs, leaving the spacecraft missing. The situation soon escalates dramatically.

Unlike the more neatly contained story of Perigee, Farside takes a more dramatic and ambitious turn. The prose and characterisations also feel more confident and engaging, as the novel escalates from a relatively low key science fiction accident story to a competent geopolitical thriller.

Also compared to Perigee, the technical accuracy has much improved. I will permit myself a tiny nitpick: “Taxi into position and hold” is outdated air traffic radio phraseology and no longer used.

Seveneves – Neal Stephenson

SevenevesIn a very near future, the Moon is destroyed, suddenly and without warning. Within a few days, scientists figure out that the seven pieces will impact each other again and again, breaking into ever smaller pieces until after two years the process reaches a sort of critical mass. Then, so many large meteors will impact the Earth’s atmosphere that it will broil, annihilating all life on Earth in an event named the “Hard Rain”. Desperate measure are implemented to launch as many people as possible into space before the end. It is estimated that it will take 5000 years until the Hard Rain abates and Earth can be made inhabitable again.

Seveneves is a very long novel divided into three parts. Part one details events from the destruction of the Moon to the Hard Rain. Part two chronicles the struggle for survival after the Hard Rain and the nadir of human population, as well as the momentous decisions at this point. Part three jumps five thousand years into the future, with Earth being repopulated and the human race split into seven races. It is an epic story focusing on themes of resilience, survival and most of all what it is that makes us human. What are the traits that make us who we are? What drives us to conflict, cooperation, competition and rationality? Seveneves asks the question: Can such traits be altered in the human race through genetic tinkering, and what would happen if they were?

In the beginning of part three, there is a feeling of disjointedness with the rest of the story, but after a while this somewhat separate story with entirely new characters starts feeling like an appropriate bookend to parts one and two, with a perspective on ancient events down the long lens of history, and with the results of the experiment at hand.

The text is littered with info-dumps, mostly about space technology. Detailed explanations about orbital mechanics and the physics of free-falling chains abound. I personally found this content very interesting, but I can understand that not all would. The prose flows easily from page to page, filling the reader with a real desire to find out what will happen on this great odyssey. For it is truly an odyssey, an epic of monumental proportions drawing the entire human race, with all its history and heritage, down to a single point, literally a single room, and then chronicling its resurgence.

Dark Lightning (Thunder and Lightning IV) – John Varley

ThunderandLightning4DarkLightningAt the end of Rolling Thunder, the great asteroid starship Rolling Thunder leaves the solar system led by the extended Garcia-Strickland-Broussard clan. The ship is a classic hollow rotating cylinder, propelled to a high fraction of the speed of light by the mysterious squeezer-bubble technology invented by Jubal in Red Thunder. As with previous installments in the series, we again jump forward a generation. The story is told in the first person by identical twins Cassie and Polly, daughters of Jubal and Podkayne. After one of Jubal’s regular exits from stasis in a “black bubble”, he screams that the ship must be stopped. Eventually he figures out that Dark Energy (catchily referred to as “Dark Lightning” in the book) may be a danger when traveling at a very high percentage of the speed of light. However as always with Varley, the story is about the people. Jubal’s scream of “Stop the Ship!” triggers shipwide unrest, and the twins are the ones who have to sort things out.

In true Varley form, the worldbuilding is first-class, detailed and intricate. The characters are authentic and easily engage the imagination. The twins are in their late teens, and as such their commentary is peppered with talk of boys and fashion, but without being annoying. Mostly it is just plain funny. After the pessimistic tone of Red Lightning and very gloomy one of Rolling Thunder, it is also nice to read an installment in the series with a brighter outlook.
