Parenthetically, the author John Sandford was born in Cedar Rapids, Iowa which is near my hometown. He and his late wife, Susan, attended the University of Iowa which is my alma mater. Sadly, Susan died of breast cancer in 2007.
If you enjoy detective stories, I highly recommend Mad River.
I am currently reading another great book called Defending Jacob by William Landay. It's a legal thriller and I can't wait to see how it ends!
