Restless, insatiably curious, Anna learns to read, and in this ancient city, famous for its libraries, she finds a book, the story of Aethon, who longs to be turned into a bird so that he can fly to a utopian paradise in the sky. This she reads to her ailing sister as the walls of the only place she has known are bombarded in the great siege of Constantinople. Outside the walls is Omeir, a village boy, miles from home, conscripted with his beloved oxen into the invading army. His path and Anna’s will cross.Five hundred years later, in a library in Idaho, octogenarian Zeno, who learned Greek as a prisoner of war, rehearses five children in a play adaptation of Aethon’s story, preserved against all odds through centuries. Tucked among the library shelves is a bomb, planted by a troubled, idealistic teenager, Seymour. This is another siege. And in a not-so-distant future, on the interstellar ship Argos, Konstance is alone in a vault, copying on scraps of sacking the story of Aethon, told to her by her father. She has never set foot on our planet.

    Across the city, abandoned factories populate the skyline; meanwhile at the shore, one strong spark, and the Cuyahoga River might catch fire. But none of that compares to what’s happening in their own west side neighborhood. The girls Phoebe and Jacqueline have grown up with are changing. It starts with footprints of dark water on the sidewalk. Then, one by one, the girls’ bodies wither away, their fingernails turning to broken glass, and their bones exposed like corroded metal beneath their flesh.As rumors spread about the grotesque transformations, soon everyone from nosy tourists to clinic doctors and government men start arriving on Denton Street, eager to catch sight of “the Rust Maidens” in metamorphosis. But even with all the onlookers, nobody can explain what’s happening or why—except perhaps the Rust Maidens themselves. Whispering in secret, they know more than they’re telling, and Phoebe realizes her former friends are quietly preparing for something that will tear their neighborhood apart.Alternating between past and present, Phoebe struggles to unravel the mystery of the Rust Maidens—and her own unwitting role in the transformations—before she loses everything she’s held dear: her home, her best friend, and even perhaps her own body.
