1) 'The Spear' James Herbert (1981)
Those glaring red eyes! That disturbingly phallic spear held by a skeletal hand! All set against an impenetrable black background! I suppose the cover artist showed the publisher a rough rendition got the rest of the week off for this work as a bonus.
2) 'Slugs' Shaun Hutson (1982)
Hokey as this novel seems now and since made into a very cheesy B-movie in 1988, perhaps the only genuine shudders are provoked by this first-edition cover art. A slug slowly nibbling the corner of some unfortunate woman's eyeball - although now I believe perhaps a pinch of salt would kill the pesky thing?
3) 'Books of Blood Volume 4' aka 'The Inhuman Condition' Clive Barker (1985)
The man's brain is exposed while his body is dissolving into ribbons, and yet his eyes are full of manic glee - he really shouldn't be enjoying his ordeal. This cover seriously scared me when I was seven but when I later discovered that the cover art was also painted by the author, I *had* to read the book just to find out whether the contents measure up to the cover. They do. (This book contains the short story 'The Forbidden' which was adapted into the film 'Candyman' in 1992)
4) 'Communion' Whitley Strieber (1988)
There's a good reason why I do not believe that the little green men will be cute, cuddly and benevolent if they visit this planet. This book cover is that reason - do those eyes say 'We come in peace'?! No, they say ,'We come to send rectal probes to Uranus!'
5) 'It' Stephen King (1988)
"Where's the clown?" you may ask. The clown owes much to Tim Curry's terrifying portrayal in the miniseries adaptation and subsequent editions later put the clown on the cover. However, this simple and very understated cover art hints at a monstrous menace hiding just under the ordinary streets where children play.
6) Spooky Stories 1 edited by Barbara Ireson (1982)
The first volume in a great anthology series (for children!) with a cover so unnerving that my mother hated it. Grubby fingernails, decayed teeth and wild staring eyes- urghhh!
7) 'Koko' Peter Straub (1988)
Not really disturbing for me when I was 10 but more grungy, grainy and very enigmatic; What or who is 'Koko'? I remember reading the back cover; its about Vietnam War veterans trying to catch a serial killer (hence the camouflage paint on the face) Thankfully reprinted in 2009, so I can finally read it to find out.
