This makes me so completely sad. Michael Crichton was the first "adult" novelist I ever read. I tackled his stuff when I was in middle school and ate it up. Admittedly, I was never a true fan: I never bought EVERY SINGLE TITLE and I only read the titles that interested me. In the last ten years, I think the only Crichton title I've read was Timeline (which I adored).
But it's sad to see such a figure in the writerly world pass on, especially one who was such a mile-marker in my formative reading and writing years.
It makes me want to read his books again.
