I have Michael Crichton's "Next" in line to read, and am also looking forward to the next and final HP book. I plan to purchase "The President, the Pope, and the Prime Minister" as well.
I am also re-reading one of my all-time favorite authors, Mary Stewart. I just finished re-reading "The Crystal Cave" and "The Hollow Hills", and have a re-release of "The Gabriel Hounds" awaiting savoring. (That last has to have one of THE BEST opening book lines of all time, or at least one of my favorites: "I met him on a street called Straight.")
I used to love Mary Stewart's books. The Moon-Spinners was made into a movie in 1964.
