I like the Scandinavian style, all those gripping storylines, but I don't like too much graphic violence. It is the same with TV dramas, I enjoyed The Killing, The Bridge etc but preferred Borgen if the truth be told.
I am currently reading Until Thy Wrath Be Past by Asa Larsson, it was 56p in the Kindle sale so worth a gamble. I am really enjoying it. I just hope it doesn't suddenly get horribly violent. I didn't like The Girl With The Dragon Tattoo.
What else might I like?
