Coldbrook

Tim Lebbon

Deep in the Appalachian Mountains, a secretive research facility succeeds in opening a gateway to an alternate Earth—only to discover that something has crossed back with them. When a devastating, reanimating disease begins to spread, the scientists and survivors of Coldbrook must confront a catastrophe born from humanity’s ambition and curiosity. As civilization buckles under the outbreak, the desperate search for the one person immune to the infection becomes a race against time. Blending apocalyptic horror, scientific speculation, and relentless suspense, the novel explores the consequences of opening doors that may never have been meant to open.
