Starfall Book 1. Starfall: A Tale in Two Eras, #1

In this first book in a four-book tale of cli-fi-meets-historical fiction, Xenia, a woman with an integrated artificial intelligence, embarks on a mission to repair a malfunctioning relay at the edge of the wilderness now called the Flood Zone. As the mission turns to disaster, Xenia and her security contractor find themselves confronting a greater mystery, one that eventually leads them to a strange town in the middle of nowhere, where nothing is quite as it seems. The town, called Harmonie, has a long utopian history.
Half-abandoned for years, it has been revived by a group of secretive scientists and artists, who are still dealing with the echoes of a long and complex American past. Its traces appear in a set of peculiar 19th-century documents that chronicle the life of a free-spirited woman, the long forgotten reformer and troublemaker Camilla Wright, which only deepens riddles lurking in the heart of the forest.
