When there is a call, there is often a response. Najeeba knows. She has had The Call. But how can a 13-year-old girl have the Call? Only men and boys experience the annual call to the Salt Roads. What’s just happened to Najeeba has never happened in the history of her village. But it’s not a terrible thing, just strange. So when she leaves with her father and brothers to mine salt at the Dead Lake, there’s neither fanfare nor protest.

Since Anabelle’s mother left for Earth to care for her own ailing mother, her days in New Galveston have been spent at school and her nights at her laconic father’s diner with Watson, the family Kitchen Engine and dishwasher, as her only companion. When the Silence came, and communication and shipments from Earth to its colonies on Mars stopped, life seemed stuck in foreboding stasis until the night Silas Mundt and his gang attacked.

The old world is buried. A new one has been forged atop the shifting dunes. Here in this land of howling wind and infernal sand, four siblings find themselves scattered and lost. Their father was a sand diver, one of the elite few who could travel deep beneath the desert floor and bring up the relics and scraps that keep their people alive. But their father is gone. And the world he left behind might be next.

A Secret Service operative and dedicated survivalist, Special Agent Del Roosevelt had a plan for every world-ending scenario and regularly trained for them all. He was even ready for a date with the hottest woman in his office next Friday. At least he hoped so. But all that training, all those rations, all that prepping? Useless for the apocalypse that actually played out. Del wakes up half-buried in a giant trash pile, missing his thumbs. And, um, covered in red fur. He's stuck in a world of fuzzy monsters, senseless violence, and cult-like crusaders.

Silas is inducted into the System, becoming the last in a long line of Earth's "forerunners." The rewards are great, but the danger is greater. We are not alone in the universe. The fate of five worlds hangs on how their forerunners perform. Will Silas have what it takes to win Earth a place in the multiverse? Or will Earth become another mining world stripped of all resources and left a barren husk floating in the cosmos?
