The second and currently last book in the Delta-v techno-thriller series by Daniel Suarez brings back the mining crew members to another adventure, this time to save their left-behind crew members before it’s too late. Being closer to sci-fi than thriller, the concluding novel still leaves a door open to a possible third novel, which bringing all the open threads to a satisfying closure.

When unforeseen circumstances during an innovative—and unsanctioned—commercial asteroid-mining mission leave two crew members stranded, those who make it back must engineer a rescue, all while navigating a shifting web of global political alliances and renewed Cold War tensions. With Earth governments consumed by the ravages of climate change and unable to take the risks necessary to make rapid progress in space, the crew must build their own nextgen spacecraft capable of mounting a rescue in time for the asteroid’s next swing by Earth.

In the process they’ll need to establish the first spin-gravity station in deep space, the first orbiting solar power satellite and refinery, and historic infrastructure on the moon’s surface—all of which could alleviate a deepening ecological, political, and economic crisis back on Earth, and prove that space-based industry is not only profitable, but possibly humanity’s best hope for a livable, peaceful future.
