I read most all types of books. I am reading George R.R. Martin's Game of Throne series. It's a long wonderful saga along the lines of Pillers of the Earth book series. The Hunger Games series are required reading in school now. I would recommend any parent or grandparent reading them. I loved the Harry Potter series.
My favorite all time books which I reread a lot are: "The Jungle" by Upton Sinclair, "The Egg and I" by Bettye McDonald, "The Good Earth" by Pearl S. Buck and "The Ladies of Missalonghi" by Colleen McCullough If you haven't read the classics books of Austen, Bronte, Dickens, do! Also John Stienbeck's "Grapes of Wrath". I loved "Hawaii" by James Michener and any of his historical novels. The characters in my favorite books seem like old friends.
