After a half-century hiatus, humanity is gearing up for true space exploration once more, but this time it won't only be nation-states taking part. Delta-v tells the story of a group of commercial space pioneers on a multi-year expedition to lift humanity from an Earth-bound species to a space-faring one.

Much like the private explorers of earlier centuries whose voyages were financed by investors, these new adventurers gravitate toward risk -- ex-soldiers, former astronauts, cavers, salvage divers, base jumpers, and mountain climbers.

As the second Age of Exploration begins, they intend to alter the trajectory of human civilization -- or die trying.

The bestselling author of Daemon returns with a near-future technological thriller, in which a charismatic billionaire recruits a team of adventurers to launch the first deep space mining operation--a mission that could alter the trajectory of human civilization.

When itinerant cave diver James Tighe receives an invitation to billionaire Nathan Joyce's private island, he thinks it must be a mistake. But Tighe's unique skill set makes him a prime candidate for Joyce's high-risk venture to mine a near-earth asteroid--with the goal of kick-starting an entire off-world economy. The potential rewards and personal risks are staggering, but the competition is fierce and the stakes couldn't be higher.

Isolated and pushed beyond their breaking points, Tighe and his fellow twenty-first century adventurers--ex-soldiers, former astronauts, BASE jumpers, and mountain climbers--must rely on each other to survive not only the dangers of a multi-year expedition but the harsh realities of business in space. They're determined to transform humanity from an Earth-bound species to a space-faring one--or die trying.
