Dark tales and a wimpy reader

What sort of book makes a grown woman sleep with her light on? I have to admit I am only three-quarters through Yrsa Sigurdardottir's book I Remember You and I am not sure I can complete it. When you get up half way through a sentence to make sure all the doors are locked and the windows closed then you know rather than enjoying the written word you are bordering on a panic attack.

Based partly in an isolated village (of course) in the Icelandic Westfjords we watch as three friends try to do up a derelict old house when they realise they are not alone. In the light of day you may accuse me of being a wimp but when you are snuggled up in bed at night all it took was a creak somewhere in my house for  me to question if my heart had stopped beating. I will finish this book - but only in daylight. If you are braver than me and love the feeling of all the prickly bits on the back of your neck standing up then check out this author.

Are there any other authors out there I should avoid reading at nighttime? I don't have the nerve endings I once had!
