Here are a few books that have frightened me (they may not necessarily be considered horror novels) -
Faith is the name humanity has given to the unknown, seemingly invincible alien ship that has begun to harass the newly emergent Commonwealth. 300 years earlier, the same ship destroyed the Sakhran Empire, allowing the Commonwealth to expand its sphere of influence. But now Faith has returned! The ship is as devastating as before, and its attacks leave some Commonwealth solar systems in chaos. Eventually it reaches Sakhra, now an important Commonwealth possession, and it seems like history is about to repeat itself. But this time, something is waiting: an Outsider, one of the Commonwealth's ultimate warships. Slender silver ships, full of functionality and crewed by people of unusual abilities, often sociopaths or psychopaths, Outsiders were conceived in back alleys, built and launched in secret, and commissioned without ceremony. One system away from earth, the Outsider ship Charles Manson makes a stand. Commander Foord waits with his crew of miscreants and sociopath, hoping to accomplish what no other human has been able to do - to destroy Faith!
Zombies have infested a fallen America. A young girl named Temple is on the run. Haunted by her past and pursued by a killer, Temple is surrounded by death and danger, hoping to be set free. For twenty-five years, civilization has survived in meager enclaves, guarded against a plague of the dead. Temple wanders this blighted landscape, keeping to herself and keeping her demons inside her heart. She can't remember a time before the zombies, but she does remember an old man who took her in and the younger brother she cared for until the tragedy that set her on a personal journey toward redemption. Moving back and forth between the insulated remnants of society and the brutal frontier beyond, Temple must decide where ultimately to make a home and find the salvation she seeks.
In a nightmarish ruined world slowly awakening to the light after sleeping in darkness, the infant rediscoveries of science are secretly nourished by cloistered monks dedicated to the study and preservation of the relics and writings of the blessed Saint Isaac Leibowitz. From here the story spans centuries of ignorance, violence, and barbarism, viewing through a sharp, satirical eye the relentless progression of a human race damned by its inherent humanness to recelebrate its grand foibles and repeat its grievous mistakes.
Insomnia has claimed everyone Biggs knows. Even his beloved wife, Carolyn, has succumbed to the telltale red-rimmed eyes, slurred speech and cloudy mind before disappearing into the quickly collapsing world. Yet Biggs can still sleep, and dream, so he sets out to find her. He ventures out into a world ransacked by mass confusion and desperation, where he meets others struggling against the tide of sleeplessness. Chase and his buddy Jordan are devising a scheme to live off their drug-store lootings; Lila is a high school student wandering the streets in an owl mask, no longer safe with her insomniac parents; Felicia abandons the sanctuary of a sleep research center to try to protect her family and perhaps reunite with Chase, an ex-boyfriend. All around, sleep has become an infinitely precious commodity. Money can't buy it, no drug can touch it, and there are those who would kill to have it. However, Biggs persists in his quest for Carolyn, finding a resolve and inner strength that he never knew he had. Kenneth Calhoun has written a brilliantly realized and utterly riveting depiction of a world gripped by madness, one that is vivid, strange, and profoundly moving.
