I also really enjoyed Canal Dreams and Whit, but found The Bridge hard going and slightly baffling, I'd stick it very much in the Kafka section of easy reading that one!
Oooh I was going to give Whit a go next. I'm currently finishing Stonemouth, which is ok, but nothing to write home about.
I downloaded a sample of The Bridge but it didn't grab me so I've left that one for the time being.
What I meant was that sometimes seeing a film prior to reading the book can make you less inclined to read it - e.g. I'm glad I read it before I've seen Craig's portrayal of Blomkvist. I fully intend to see the movies now I've finished the series.
I love the Roy Grace series but if you want something in the same mold but with more grit and some heart stopping moments, read the Harry Hole series by Jo Nesbo. Bloody brilliant.
The Book Thief by Markus Zusak.
I passed this around when finished and we still talk about it now. Magnificent
"The hundred year old man who climbed out of the window and disappeared" by Jonas Johanson - odd title, fantastic holiday read, you won't regret it.
