I'm an avid reader and will give pretty much anything a try with the exception of the Harlequin type romance novels - I just can't get into them.
Some of my personal favorites are: Harry Potter books, John Grisham's earlier works, Dead Men do tell Tales by Dr. William Maples, pretty much anything by Nora Roberts, some Debbie Macomber (although I think she tends to have too many characters in each book), Patricia Cornwell, Michael Crichton, and on and on and on. I love forensic novels and mysteries.
