Karin Slaughter for me. I read the first 3 books of the Sarah Linton series and gave up about a quarter of the way through the 4th because essentially they are all exactly the same thing.
Good books, but in hindsight the only two that I think you really would benefit from reading in sequence if you want to get into the series is the first two because of the back story and introduction of the main characters, after that you can pick any of the other books and they are essentially all the same thing.
Murder happens around about page 20, in the middle throw in a few wrongly accused townsfolk and a bit of a weak love story and murder is solved around page 200, in every....single.....one.
Why she didnt just write one maybe two epic books rather than just dragging the same up over and over through what is it 8 books? i dont know.
meh
