Set several years in the future, A Light Not of This World is about nuclear attacks on the United States by a small group of terrorists, the hunt for them before they explode more bombs, the retaliation against their supporters and suppliers, and the heroic actions by Americans in response to the tragedy. This book describes a real war on terror and all its ramifications. This book was first published in 1910. This edition contains revisions and updates necessitated by events that have occurred since 2010, and to correct some minor errors. However, nothing has occurred since 2010 that makes the story any less plausible today. If anything, real events are tracking fairly closely to the future fictional situation described in the novel.
