The Complete Comet Cycle

“Great characters, fine writing, totally engrossing.” —Stephen King

The Ninth Metal • The Unfamiliar Garden • The Sky Vault: All three brilliantly inventive, acclaimed novels in one essential edition. An immersive listening experience featuring narrators Julia Whelan, Will Coyler, and Michael David Axtell.

It began with a comet. The world watched it pass—a spectacle of light. A year later, Earth crossed through its debris field. That was when everything changed.

Collected here for the first time in a single volume, Benjamin Percy's acclaimed Comet Cycle trilogy maps the fallout of one celestial event across three landscapes, three communities, and three visions of what humanity becomes under pressure.

In The Ninth Metal, a mysterious new element rains down on a small Minnesota mining town, triggering a gold rush fueled by greed, violence, and the dawning suspicion that omnimetal is something far stranger than a resource.

In The Unfamiliar Garden, a detective and a biologist — two estranged parents still grieving a lost daughter—converge on a new threat spreading through the rain-soaked Pacific Northwest: a parasitic fungus with an intelligence all its own.

And in The Sky Vault, the truth behind Comet Cain finally surfaces in the wilderness of Alaska, where a secret buried since World War II and the machinations of the U.S. government push ordinary people toward an extraordinary reckoning.

Together, these standalone Comet Cycle novels create a striking portrait of a world both undone and reimagined.
