Edge of the Known World: A Novel

Fans of Margaret Atwood and Emily St. John Mandel will be gripped by this high-stakes, timely, and deeply human literary thriller about hidden identity, genetic surveillance, and the difficult choices between love and family.A USA Today bestseller and winner of the American Fiction Awards and Chanticleer International Book Awards. In a near future where DNA tests are used at ID checkpoints, brilliant Alexandra Tashen is hiding in the open. After a blissful childhood on a Texas ranch, she learned of the secret in her genes—a harmless inherited marker and ancestry that would get her deported to a brutal regime and likely death. Her adoptive father’s experimental gene therapy masks her marker, but not completely. Every security check is a one-in-ten chance of getting caught. When her father vanishes, Alex risks everything in a headlong and often comic search across nations. A volatile love triangle develops with two brothers—one a disgraced intelligence officer, the other a damaged, charismatic diplomat—each guarding secrets of their own. As betrayals mount and the secrets unravel, Alex must confront the confounding choices between love, family loyalty, and moral obligation. Edge of the Known World blends the tension of a global thriller with the heart of a love story.
