I Am Legend by Richard Matheson (1954): Matheson's first novel begat Night of the Living Dead which begat pretty much every zombie apocalypse of the last 50 years on TV, in movies, and in print. While I Am Legend has been adapted for the screen three times, no one has ever captured its portrayal of abject loneliness. Humanity may have been devastated by a plague of vampirism, but protagonist Robert Neville's tortured thoughts and actions make the novel special as a work of literature and not just as a massive cultural influence.
The novel may be set in the late 1970's, but Neville is very much a 1950's Everyman figure. He dwells in a suburb of Los Angeles with a wife and a daughter. He carpools to work with a neighbour. He drinks a lot of cocktails. But a vaguely defined war in which Neville himself served overseas may have unleashed the disease that caused all those stories of vampirism in Eastern Europe during the 18th century. In the now of the novel, which we join in media res, Neville is alone but under siege by multitudes of vampires every night. He's turned his house into a fortress. And every day, he drives around pulling vampires out of their hiding places and staking them to death.
For a short novel (maybe 70,000 words soaking wet), I Am Legend is packed with heady goodness. There's the characterization of Neville, who reveals hidden depths as we spend more time with him. There's Neville's scientific approach to understanding just how these vampires work, and what works against them, and why. There's the back-story of the fall of society, with mass graves and an incompetent government and growing paranoia.
And there are the vampires themselves, split into two groups: living vampires who've been infected and changed, and dead vampires who continue to be animated by the contagion. Both die when you stake them, though the second group occasionally disintegrates. Neville's quest to understand what's going on in a scientific sense helps him to hold off the encroaching loneliness. He's Robinson Crusoe with a microscope and no Man Friday. He doesn't even have a parrot to talk to. But he does have his books and his classical music.
The list of later works with I Am Legend's DNA in them could probably fill a book. From Matheson's succinct glimpses of plague-fueled societal breakdown come World War Z and The Stand and so many others; from the monsters whose origins seem to be scientifically explicable come legions of infected zombies and vampires whose blood teems with bacteria or viral loads instead of magic. It's the loneliness of Neville that hasn't been replicated that often in subsequent works of horror.
Thankfully, there's also grim humour throughout the novel, much of it supplied by Neville's dead but lively vampire neighbour Cortman (!), who yells endlessly at Neville by night but whose diurnal hiding place Neville searches fruitlessly for by day. Good old Cortman. He never shuts up. Highly recommended.
Skeletons by Al Sarrantonio (1992): This wild, woolly, and marvelously imaginative novel takes the bare bones of the standard zombie epidemic narrative and makes them new. I've always viewed Al Sarrantonio as being a much more gifted writer of short stories than novels, but this dark fantasy novel is a real treat.
One day, all the dead on Earth rise from their graves. But they do so as skeletons held together by some inexplicable, translucent force field that resembles what they looked like (and what they were wearing!) when they died. Even if they died 3000 years ago. Even if they were dinosaurs.
And the skeletons possess their old personalities with one key difference: they're possessed of an almost-irresistable urge to kill the living. When the living die, their dead flesh vanishes and they, too, become Angry-Ass skeletons. It's the new circle of life! The skeletons can be killed, at which point they disintegrate into dust. But there are a lot of them. There are even insect skeletons. Ha ha whee!
With four first-person narratives telling the tale, Skeletons anticipates Max Brooks' multi-viewpoint World War Z in its structure to an extent, though certainly not in tone or content. We may start off with an apocalyptic war between the Living and the Dead, but the narrative soon starts building another narrative within that: a mythoreligious tale of a world periodically cleansed by a flood... of skeletons. It appears that God may have hit the reset button for humanity (not to mention most other species that aren't lucky enough to be plants). And not for the first time.
Sarrantonio's myth-building is faithful to the often unpleasant ramifications of myth and legend. There's a critique here of vengeful gods and chosen ones, of religious fanaticism and stories that reduce women to super-wombs. But that critique exists within a novel that scrupulously follows the ethos it creates to its logical end.
Though there's still room for a comical gorilla, a faithful wolf, and a drugged-out music promoter who somehow finds himself still human and stuck in the middle of things as the apocalypse heads to its end. Apocalypse, meaning 'the unveiling.' What's more unveiled than a person's naked skeleton?
And one first-person narrative consists of Skeleton Abraham Lincoln's story in the New World Order. Sarrantonio anticipates all those comic horror novels involving famous people, famous literary works, and newly added monsters. Though in this case, he's Abraham Lincoln, Human Hunter. It's a swell, bracingly comic novel. Highly recommended.
