The Eschatologist [EPUB ebook] 

David Brewer is trying to keep his family alive in a world torn asunder by a Biblical apocalypse. Yet there is salvation, in the guise of a stranger who offers survivors sanctuary. All they have to do is declare their faith in God’s final – and bloody – plan. 'Madness and murder and miracles all abound in The Eschatologist. Reminiscent of Barker’s early work, the end of the world has never been so bleak.’ -Tim Marquitz, author of the Demon Squad
