39. Tourist Season, by Carl Hiaasen
Brian Keyes, a former reporter turned PI, is hired to investigate the case of a Cuban man arrested for murder. It turns into a much larger case involving a former colleague, a wealthy Seminole, an ex-football star, and the world's most incompetent terrorist.
This is Hiaasen's first "only in Florida" novel, and one of his best.
40. On the Beach, by Nevil Shute
Nuclear war has come and gone, and the people of Melbourne, Australia, wait for the end as the radiation moves steadily south, killing everyone in its path.
This is honestly one of the most depressing books I've ever read, and the ending is a real tearjerker. It's about nothing less than the end of the world.
