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.

Booktrack Edition: The Tower of Babel is the greatest marvel in the world. Immense as a mountain, the ancient Tower holds unnumbered ringdoms, warring and peaceful, stacked one on the other like the layers of a cake. Soon after arriving for his honeymoon at the Tower, the mild-mannered headmaster of a small village school, Thomas Senlin, gets separated from his wife, Marya. Senlin is determined to find Marya, but to do so he'll have to navigate madhouses, ballrooms, and burlesque theaters. He must survive betrayal, assassins, and the illusions of the Tower.

The world outside has grown toxic, the view of it limited, talk of it forbidden. The remnants of humanity live underground in a single silo. But there are always those who hope, who dream. These are the dangerous people, the residents who infect others with their optimism. Their punishment is simple. They are given the very thing they want: They are allowed to go outside.

Most days, Sarya doesn't feel like the most terrifying creature in the galaxy. Most days, she's got other things on her mind. Like hiding her identity among the hundreds of alien species roaming the corridors of Watertower Station. Or making sure her adoptive mother doesn't casually eviscerate one of their neighbors. Again. And most days, she can almost accept that she'll never know the truth - that she'll never know why humanity was deemed too dangerous to exist.

War heroes aren't usually called out of semi-retirement and sent to the far reaches of the galaxy for a routine investigation. So when Colonel Carl Butler answers the call from an old and powerful friend, he knows it's something big - and he's not being told the whole story. A high councilor's son has gone MIA out of Cappa Base, the space station orbiting a battle-ravaged planet. The young lieutenant had been wounded and evacuated - but there's no record of him having ever arrived at hospital command.
