I forgot - I also enjoy Nicci French - Killing Me Softly (such a clever title) was unputdownable; if there's not such a word, there ought to be!
Cat's Eye by Margaret Atwood was my favourite of hers and one of my very favourite books but I agree, some are hard and I haven't enjoyed all of her books - found The Blind Assassin impossible to follow, comprehend or like, despite persevering.
I'll look out for Tess Gerritsen.
Happy Reading, Jenni x
