On a dead planet, a captain and his crew encounter an unknown evil in this sci-fi adventure from the New York Times–bestselling author.

No life can survive on Unseeli—at least, not anymore. This little planet on the edge of the Empire has no oceans, rivers, or lakes—only an endless forest of metal trees, tall enough to scrape the stratosphere. Ten years ago, the indigenous people stormed out of the forest in rebellion, and Captain John Silence was there for the massacre that left Unseeli's natives extinct and the planet completely lifeless save for the engineers who mine its invaluable metals. When the mining operation goes off the rails, Silence will be called back to the world that still haunts his nightmares.

The miners have erected a force shield around the planet and cut off all communication with the Empire. Backed up by a few professional killers, Silence lands at the mine in hopes of discovering what's gone wrong. Getting into Unseeli will be tough—but getting out could prove impossible.
