Delta-V By Daniel Suarez Dutton, 2019

Super-skilled cave diver James Tighe is no sooner towelled off from a hair-raising cave-disaster rescue in the opening pages of Daniel Suarez’s new book Delta-v than he finds himself the guest of eccentric billionaire Nathan Joyce and getting a lecture from Nobel Prize-winning economist Sankar Korrapati about US financial policy and the nature of debt-based banking. It’s just a bit of a curveball; Tighe won’t be the only one who’s a bit disoriented.

Korrapati patiently explains that his financial models clearly show that the global economy will soon fracture and fall apart unless this enormous debt bubble is popped somehow - and there’s nowhere to go but up. “Let me get this straight,” Tighe says, “you’re saying humanity must expand into space - not for the sake of science or exploration, but to stop the banks from going broke?”

That’s about the size of it; Nathan Joyce wants to hire an experienced cave-diver to lead a mining team to a distant asteroid. Tighe immediately points out that it took him years to accumulate his cave-diving experience and that he knows nothing at all about space travel. He’s informed that since he’s a character in a thriller, this won’t be a problem, and we’re off to the races: cue the assembling of a wacky crew of characters, cue the percolating of connected sub-plots, and of course cue the dumping of copious amounts of exposition.

For instance, the question naturally arises: if you’re interested in off-worlding that expanding bubble of debt (and aren’t even remotely considering, you know, regulating the banks), why not colonize Mars? True, it has only about a third of Earth’s gravity, but one defender of the idea says we can’t be sure that would be much of a problem - and gets a wad of exposition in response:

“We have some idea. The human body evolved over millions of years to function in one Earth gravity. Astronauts suffer health issues from just a few months in microgravity ... Bone and muscle loss, eye damage - to say nothing of the viability of pregnancy in a low-gravity environment. You’re willing to send people all the way to Mars before we find out if that’s a problem? Why not build a station in cislunar space that can rotate to simulate various levels of gravity long-term before we send people to colonize Mars? Oh, but then, I guess if you did that, you’d be halfway to building a space colony, wouldn’t you?”

Readers are taunted a couple of times with the vision of a novel about colonizing Mars, but what they get instead is a big, boisterous book about mining an asteroid in order to shore up banking collateral. The mission is intensely predictable; Tighe himself an action-hero mannikin; the Act Three surprise isn’t actually surprising; and there are stretches of operational chatter:

We are at t minus ten minutes local time for a 1.9-kilometer-per-second postinjection burn.

“Fuel systems go. “Engines are go. “Comm systems are go. “Telemetry looks good.

A verbal countdown began ten seconds before the engine ignition - which mission control called correctly despite the transmission delay, and at t minus zero a gentle vibration reached the crew as they were gently pressed into their seats. After a ninety-five-second delay the radio confirmed what they already knew ...

“We have main engine start. “Throttle at 30 percent. “Trajectory normal.”

In other words, very little in Delta-v should work. But Suarez is an old and practiced hand at creating silk purses out of sow cave divers. Delta-v never falters because it never doubts its own storytelling virtue; it’s a purely silly and purely effective thriller, exactly the kind of plot-driven potboiler that would once have been put before the reading public in a $3 paperback with an eye-catching cover. The cover of Delta-v is a beautifully eye-catching thing, although the book itself is nearly $30. There’s that ever-expanding bubble again.
