Query: Apocalypse Now!

The "guts" of this book are every bit as creepy and frightening as the cover. I read this book almost a dozen years ago when it was first published and it gave me nightmares. After discovering this new edition, with vastly improved cover art done by Mark Rogers himself, the nightmares returned. I have loaned my battered, out-of-print first edition to almost every friend I have and everyone of them thought it a great book.The Dead is terrifying on many levels, but the author's ability to make the premise of corpses clawing up out of their graves, bent on maiming and torturing the living seem possible and believable scared me more than anything else.The story moves along at a furious pace, punctuated by gun battles, martial arts action and conversations with the damned undead. The theology, on which the book is based, is well thought out and argued over from many different viewpoints by the characters, keeping the book from becoming too preachy.I can't recommend it enough.
