**"Laudable worldbuilding...the prose impeccable...sublime denouement [ending]..." —**Kirkus Reviews

The star in the night sky isn't moving. They are.

As one star blazes ever brighter in the night sky, Sargon—a former millwright who renounced invention—and Angora—a brilliant scholar—dig into the depths of their seemingly natural world and delve into ancient texts in search of answers. They deduce the shocking truth: their cylindrical world, Areta, is a gargantuan vessel that has been sailing through the cosmos for countless generations. And it is on a collision course with a sun.

The only hope for survival lies with Sargon and a small team of millwrights he assembles. As time runs short, they must construct the seemingly impossible—while flouting norms and risking exile of the ruling council.

Set in a society rooted in the ancient Near East and Greece, Areta's culture contains ingenious, handcrafted technology. In this world, where women may tower over men and reproduction is divorced from pair-bonding, young sirenas prowl moonlit streets to claim their genetic futures, leaving tokens for the men they've chosen. But when Lilit's awakening powers blur the line between seduction and coercion, desire itself becomes dangerous.

What if these psionic powers are not a flaw in humanity's design but its future?
