In the aftermath of a devastating tsunami, an exploration vessel known as the Derleth begins sending an automated distress signal from a remote atoll in the Bering Strait. The only problem is that the Derleth has been missing for 40 years. Marine biologist Moriah Lamb joins the Carpenter Salvage team to recover the Derleth’s dead...only to find that in this remote part of the Arctic Circle the dead have plenty to say to the living...Joe Hill and Stuart Immonen’s Plunge into terror begins here!

After discovering a corpse upon the Sinnikik Atoll, Moriah Lamb leads a team to hunt for other castaways, while Gage Carpenter begins the exploration of the ghost ship Derleth. But there’s something down there in the icy darkness of the Arctic sea, something that doesn’t want to be found. And it isn’t any safer on land. There are things waiting for the search party in the mountain caves, things that were once human...and aren’t quite anymore.

The long-lost crew of the Derleth emerges from the wind-scoured stones and twisted pines of the Sinnikik atoll, looking not a day older than when they disappeared 40 years before. They come bearing impossible, dizzying gifts for their rescuers. But at what price?

Moriah, Bill, Russell, and the rest of the MacReady’s crew get an unexpectedly intimate tour inside the minds of their eyeless new friends. Meanwhile, Lacome does the math and comes to an alarming conclusion.

The crew of the Derleth have been generous hosts. They’ve given Moriah, Bill, Gage, and the rest of the MacReady’s crew several incredible gifts. They’ve solved problems humanity has grappled with for ages, shown us ways to power the entire world for generations. And they’re offering even more. All they want is one teensy-weensy little favor in return from the MacReady’s crew: open the hatch.

Sixty fathoms below the ocean’s surface, a massive hatch waits to be opened...Something within wants to emerge; wants to be born; wants to rise; wants to feed. The child is coming, desperate to fill its belly-by devouring reality itself!
