X doesn’t have a name. He thought he had one—or many—but that might be the result of the failing memories of the personalities imprinted within him. Or maybe he really is called X. He’s also not as human as he believes himself to be. But when he discovers the existence of another person like him—above ground, outside the protection of the Warren—X must learn what it means to be human...or face the destruction of their two species. “A suspenseful, darkly comic tale...The Warren is chilling because X’s situation is not only impossible but truly, inherently irresolvable. It ends as all horror stories should, with a question mark.” —The New York Times Book Review |
